We just bought this car cheap hoping that it would get my wife to and from college as she is at the end of he program. Right now I am out of work and we really don't have any extra money, it was all that we could do just to buy this car.
It is a 1996 Chrysler Cirrus LX 2.5L 6cyl. with 118000 miles. When we test drove it it seemed to run fine. The only thing that we noticed was a whining noise from the engine which got louder as you accelerated. However the previous owner pointed out that one of the air inputs was missing a gasket and two bolts. He even moved it around and showed us that it made it sound better when it was in place. We figured this an easy fix and other than that it seemed fine. My father who knows a little about cars said that this wouldn't be much of an issue. Myself I am clueless for the most part.
After three days of driving the car under the same conditions as we had trouble finding the bolts we needed, the cars troubles began. The real issue is that when you first press the gas to accelerate it is sluggish and acts as if it is about to stall but doesn't. After around 30 seconds of this suddenly it would go fine like it was prior to the problem. It would accelerate up to 55 with no problem. However as soon as you stopped again the same problem happened again.
We talked to my neighbor who knows a lot about cars and he felt confident that he could correct the problem. He hooked a pocket scanner to the car and only came up with one code(air mass flow sensor). He felt strongly that we needed to replace the crank shaft position sensor after doing some research online. We did this and noticed a very small change. At that point his scanner no longer pulled that code, it now pulled three codes having to do with the throttle. This led him to believe it to be the throttle position sensor.
After the first part not affecting much I was determined to get a better idea from researching online as well. After several hours of doing so I found several different possibilities including the throttle position sensor. Also I came across information about getting codes from the check engine light which showed up 33(A/C clutch relay)(in which the air does not work and from what I found was a common error in that case) and code 24(throttle position sensor not getting correct voltage). This sold me that it must be the throttle position sensor, so we replaced it s soon as we could get the part. We noticed a big change, however the problem still remains, just not quite as bad.
Another thing I have noticed is that when I accelerate I really didn't notice it shifting gears. My neighbor said that he thought it was shifting fine. The dashboard gauges don't always work and when I drove it they were, while when he did they weren't. When I drove the RPM gauge showed a steady increase up to just about the red line driving at about 55 MPH. I am not positive if it was reading correctly, or if it was or was not shifting. It didn't really seem to shift like the other cars that I have driven.
There are a few other things that we have noticed in trying to figure out this problem. The car seems to be leaking some kind of fluid to the muffler causing smoking from it burning off, when we checked the spark plugs they were getting a spark however, we could only get to three of them, and two of them were covered with oil. Our neighbor said this meant that it needed new valve cover seals. Supposedly the person we got the car from just did this so I thought maybe he just was not able to get the oil out of the chamber and thought that it would burn off over time. Also the battery terminal only has a few threads and has to be tightened just so to stay tight, it is also a bit rusty. We planned on replacing the bolt and cleaning up the terminal today but when we went to start the car it didn't start, it just clicked. Assume the battery is low, and just needs to be jumped.
Anyway that is where we stand now, frustrated and back without a ride. Our neighbor has helped so much I hate to ask him for more help, though I am very grateful as I am sure if I had those parts put in at a shop it would have cost quite a bit. Still unless I just go with the 10-15 other things I have read it may be I am at a loss.
Hopefully someone can pinpoint the problem from what I have said. If I could give a donation I would, but we really need every penny for whatever else we need to do to get the car running. As soon as we have money to donate we will, this site is definitely deserving as it really seems to be the most helpful one out there. If anymore information is needed I will do my best to get it to you.

Hello and thanks for donating!


So the main issue you are having seems to be with it acting sluggish, no power and intermittent stalling, correct? The first thing I see is that you never mentioned that the air intake was fixed. If there is a leak in the air intake system then it can cause a lot of issues, including the symptoms you describe. The engine needs a certain combination of fuel and air to run properly. With this leak, it is not getting the air it needs and will run poorly. I would also assume that is the reason the mass airflow (MAF) sensor code came up on the scanner. Anytime there is a leak in the intake system the MAF sensor code usually appears as a result.

We just took care of the leak Monday. We also put in a new speed output sensor and added a new ground to the computer though it is only attached with one bolt, so as soon as we can come up with another we will be putting another on.

We also put some fuel additive in, along with some additive for the transmission fluid and oil. This is where we stand now. It seeems to have helped, but still is doing the same thing. It just doesn't go if you press the pedal very much, and still seems to be staying in first gear.

When you have it in park it barely does this. It idles fine. My neighbor and I are at a loss. He is sure it has to be some sensor because when it does go it seems to run well, other than not seeming to shift.

Also now the code scanner is pulling up code 1768(transmission control module). I am hoping if this is the problem it is something as cheap and easy to replace as the other parts.

We really appreciate all the help you can give.

I just drove it again to see if there was any change and it seemed to be a bit worse again. Also it is shaking a little around 25. When I drove it yesterday and it seemed better it was in the morning and not too hot as it is now in FL, not sure if that means anything.

Also now the check engine light is back on flashing code 43 which I haven't looked up yet.

A friend suggested Sea Foam in the vacuum but Iam not sure how to do this?? or if it would help?

Code 43(misfire), came up 2 times. Guessing it has to do with the 2 spark plugs having oil on them? Planning to replace the valve cover seals and gasket, along with the intake gasket, and plug wires in the morning. Will be taking a look at the distributor too. Hopefully we are getting somewhere. When the guy sold the car to us he said he just replaced the seals, in my language that must have meant the seals need to be replaced.

The price of this car just keeps rising.

Hi JDeese

Code 43 is a misfire code and is not conclusinve as it can be any of the 6 cylinders or combinations. An OBD-II reading would show a more accurate diagnosis of which cylinder is misfiring.

You are correct about the possibility of the cylinders having oil at the spark plugs causing the misfiring and since you have aproblem, it is best to get it resolved first to test.

As to the transmission not upshifting intermittently, when engine performance is poor, ie you have a bad misfiring, the trans would tend to not upshift or upshift very late.

Get the misfiring problem resolved and retest to see if the problem goes away.

Autozone provides free scanning services. Get them to check for you and if there are any other trouble codes, let us know the exact trouble code so we can understand the problem better.

OK, so now we have changed the valve cover seals and gaskets, spark plug wires, and intake gasket. We went ahead and replaced the distributor and rotor as when we checked it is was obvious that it needed to be replaced. The good news is no more hesitation, and the check engine light is not on.

Unfortunately it still is not be shifting out of first gear. My neighbors OBD2 scanner is still pulling code 1768(I believe the transmission control module). It also seems to be running hot though the gauges don't show this, but the coolant is gurgling in the overflow after a short ride to be sure it was running better.

Prior to all of this it did seem that the car was shifting gears oddly. Not that it was making noise or any shaking just that it seemed to be shifting a bit much. It is kind of hard to explain as I didn't really drive it too much to see exactly what was going on, and my wife can't really explain it.

There are some quirky things going on with the lights, and the A/C switch relay. Can't imagine that they are related to the shifting though, but knowing how many sensors this thing has I don't know if there is a link somehow.

In the past I have gone through transmissions going before and they have always been very noticeable that it was a transmission problem. This really seems to be something electrical that just is not working properly. Hopefully someone has some idea as we have pretty much run out, unless we can find some other sensor that controls the transmission.

Like I said though it is accelerating good, and sounds much better now.

For the coolant to be bubbling out to the recovery tank without signs of overheating, the likely cause would be a bad radiator cap.

DTC P1768 = Code 15 for 2 digit codes. Here are the diagnostic procedures.

TEST 15: RELAY OUTPUT ALWAYS OFF

1. Turn ignition on. Disconnect transmission control relay. Measure voltage between ground and fused B+ (battery positive) circuit in relay connector. If voltage is greater than 10 volts, go to next step. If voltage is not as specified, repair open in fused B+ (battery positive) circuit.

2. Turn ignition off. Measure resistance between chassis ground and ground circuit in relay connector. If resistance is less than 5 ohms, go to next step. If resistance is not as specified, repair open in transmission control relay ground circuit.

3. Turn ignition on. Connect a fused jumper wire between fused B+ (battery positive) circuit and transmission control relay output circuit in relay connector. Using scan tool, observe switched battery voltage. If voltage is greater than 10 volts, go to next step. If voltage is not as specified, go to step (7).

4. Remove jumper wire. Turn ignition off. Disconnect TCM harness connector. Measure resistance between ground and transmission control relay control circuit at TCM harness connector. If resistance is less than 5 ohms, repair transmission control relay control circuit for a short to ground. If resistance is not as specified, go to next step.

5. Measure resistance of transmission control relay control circuit between TCM harness connector and relay connector. If resistance is less than 5 ohms, go to next step. If resistance is not as specified, repair open in transmission control relay control circuit.

6. Reconnect transmission control relay. Connect a fused jumper wire between battery voltage and transmission control relay control circuit at TCM harness connector. Measure voltage between ground and transmission control relay output circuit at TCM harness connector. If voltage is greater than 3 volts, replace TCM. If voltage is not as specified, replace transmission control relay.

7. Turn ignition off. Disconnect TCM harness connector. Ensure fused jumper wire is still connected between fused B+ (battery positive) circuit and transmission control relay output circuit in relay connector. Turn ignition on. Measure voltage between ground and both transmission control relay output circuits. If voltage is greater than 10 volts at one or both terminals, replace TCM. If voltage is not as specified, repair open in appropriate transmission control relay output circuit.

Okay, my neighbor says that none of this should be a problem to check. Only we don't exactly know where or what exactly we are looking for. We tried to look the TCM up on a parts site but could not find it.

Also, we are aware that there are two speed sensors and are wondering if it is possible that maybe it could have something to do with the speed input sensor; since we have already replaced the output sensor. We found that part so we know what it looks like, just don't know where to find it in the car.

So if you could let us know where the TCM is, and whether or not we should bother with the other speed sensor. If we should replace the other speed sensor we would need to know where that is as well. Thank you very much for your time.

I found a picture of the TCM and I am pretty sure it is the computer under the hood. The ABS controller is clearly marked so I am pretty sure it is the one that I added a ground to.

We are going to go ahead and go through the steps, hoping that we don't have to replace the TCM. From what I can see it would run from $100-$300, which is getting pretty pricey after all of the rest we have done. Hopefully it is just the ground or relay.

Also after driving it a bit the check engine light still is not on. Just to check I went through the on-off-on-off-on process again, and it isn't showing any codes there. After we check it out I will let you know how it came out.

It was the relay. Wow, thank goodness. That was one of the first places we looked and it was fine. I don't know but I really appreciate the help. It is running great now, like new. Hoping to sell it and make some money out of it from all that we have done.

From here we have a slight A/C issue, might be a relay too?? I think we have that one covered. If not I will definitely look to 2 Car Pros, and my neighbor for help.

Thank you all greatly!

Everything has been going well. Tonight the check engine light came on though, code 72(catalytic converter circuit). I am hoping this isn't something that is going to cause major problems. They don't do emission tests in my area, so that is not an issue. Could this cause any other problems with how it is running?

When the CEL turns on, the concerned sensor would be deactivated and the backup system for it is used.

For the catalytic converter it is not going to cause much problem but it might be clogged too badly to reduce the exhaust flow and this would affect the performance and fuel consumption.

Apart from that it is notn going to cause much problem.

Well it had been going good all this time until today. My wife made it almost home everything seemed fine, when the car just suddenly decellerated to a stop. It made no strange noises, when she pressed the gas nothing. Seemed as if it ran out of gas. The oil light came on despite the oil being fine. When she went to start it again it would turn over but died out after 5 seconds.

It was a very hot day today, however there was no sign of overheating. After it cooled down it started up and again seems to run fine. I drove it a bit and the only thing I noticed was when I pressed the gas really hard it hesitated a bit the first time. It was shifting fine otherwise.

After driving it a bit I let it idle in the driveway. There I noticed it sputtering occasionally very slighly. The odometer was off but came back on, the RPM gauge hasn't been working since we have had it running. The check engine light continues to show code 72, but now is also showing 31. We have already discussed 72, but I am trying to find what code 31 is. One thing I came across mentioned limp mode, but I don't know if that was a reliable source.

From what I have learned of limp mode it would not shift. We have discussed that earlier in this forum. Anyhow my wife is now pregnant and in school. Needless to say we need the car to run good for us now. Hopefully it is something simple and cheap. Maybe taking off the catalytic converter and cleaning it out?? Please let us know what you think, if you can help maybe we will let you name the baby. Wish we could offer another donation.

My neighbor put his pocket OBD2 tester on it and it pulled two more codes. 0420 and 1768 (catalyst system efficiancy below threshold bank 1 and manufactuers transmission control). Also found on your site that check engine code 31 is (purge solenoid circuit open/or short). Looking into the purge solenoid it looks to be another sensor. If this is causing the problem I would think it would be an easy fix.

These things and the fact that it ran after cooling off have me thinking this all must have to do with the temperature. Hope all of this will give you a good idea of what the problem is.

Code 31 can mean a few different OBD II codes namely,

P0455 = Evap Leak Monitor large leak detected.
P1486 = Evap Leak Monitor pinched hose found.
P0442 = Evap Leak Monitor small leak detected.
P0441 = Evap Purge Flow Monitor failure.
P0443 = Evap Purge Solenoid Circuit.

The Obd II scanner did not show any of the codes mentioned above so it is not going to be easy.

P1768 is not found in our database. Reconfirm the code.

Ersase the codes and get a free scan done at any of your local parts stores and let me know the exact trouble codes.

Well unfortunately we could not get the car down to the auto parts place to have them run diagnostics. However my neighbor said the diagnostics tool he has pulls the same codes, that theirs just includes a detailed explanation of each.

My wife had tried to make her drive to and from school again. It made it there in the morning. However it stalled the same way again on the way home. I told her to find a halfway point between school and home to stop on her way home as I knew it would be hot. She didn't do this and we had to tow it home.

When she got home we left it until it cooled down around 6 or 7. Then we tried to take it to the auto parts store, but it broke down after about 2 to 5 minutes of driving. This time it stalled out differently than the other two times. It seemed to go back to hesitating to go again prior to stalling out. Then when trying to start it again it would go back to turning over and shutting right down. She let it cool down thinking we could get it home but it wouldn't make it more than a couple blocks at a time.

So today we decided we were going to get under the car and have a look at the catalytic converter. I had read about hitting it with a rubber mallet, so I tried this. I also checked under the hood and found that one of the hoses connected to what I had found to be the purge canister solenoid was cracked and disconnected from the valve in the line to check the pressure. I reconnected it assuming this had to be why the check engine light came up with the purge canister solenoid code.

I also noticed the check engine light was back on, since my neighbor wiped the last codes and figured it would just be the same codes again. However the other codes didn't even come up. This time code 51 came up (oxygen sensor running lean). My neighbor also ran a diagnostic check and his code reader pulled up 0171, which I haven't checked yet.

Anyhow that is where we stand, not sure what to do next. Someone told me to drill holes in the catalytic converter and back further in the exhaust to check the pressure. Not sure if it is something I can do or not. Anyway any further information would be appreciated as I am continuing to learn more about the car and find the solution.

By the way for anyone wondering where the purge canister solenoid is it is right next to the distributor cap, below the steering fluid reservoir. It has to hoses and a plug going into it.

Symptoms indicates a possible fault with the Mass Air Flow sensor and I would suggest checking that. Sometimes when a component is failing, it does not throw any codes as it could be intermittent.

P0171 is quite often related to MAF.

We will definitely look into that. In researching the problem I have come across this being a solution. However we have also come up wirth the oxygen sensors causing a lot of these problems.

As a matter of fact, both of them seems to act as a couple, they tend to go hand in hand.

Quite often the O2 sensor would throw a trouble code.

If you are able to get onto a scanner to retrieve the freeze framedata, that would be the best way to understand what could be wrong.

What are the chances that replacing the 2 oxygen sensors will just be a waste of time and money? Is there any way other than freezeframe data to troubleshoot this problem? My neighbor thinks we should drop the muffler system down and knock out the catalytic converter with anything we can fit in there. We just need it running again to get us to our appointments. The kids are starting school soon and the doctors is 40 miles away.

We already got new oxygen sensors but I am worried that if I put them in it may not solve the problem. That would be nearly 100 dollars that could be spent elsewhere, like school supplies for the 4 boys. Is there something we should try first?

Replacing the O2 sensor is not likely to resolve the problem as O2 sensors would not normally cause the engine to stall and cannot be started.

You need to perform diagnostic test when the engine stalled and could not be started. Find out if it is fuel or igniton sparks that is causing the problem. Without localising the source, it would be looking for a needle in a haystack.

I am a little confused. If it starts and runs fine until it gets hot wouldn't that somewhat narrow down what it could be? How could it be not getting fuel and spark other than one of the sensors overheating and malfunctioning?

Could the hose connected to the purge canister solenoid having come off caused this? Now that it is back on I tried idling in the driveway for a while pressing the gas a bit to try to get it hot, then drove it around the block a bit with no problems. Just don't want to get so far we will need to tow it again. The check engine light didn't come on.

Have also tried pinching the hoses going into what Iam pretty sure is the MAF sensor, in front of the engine. This has no effect on how the car idles, which seems strange to me. But then again I don't know much about this.

If the engine is stalling after heating up, it should be temperature related and items to look at are :

1. Engine Coolant Temperature Sensor.
2. Ignition coils.
3. Wire harness connectors.
4. Fuel Pumps

You need to confirm what is missing when it stalls and could not be started, fuel or ignition sparks.

Still can't get the car to a shop. It will drive around the block twice. As you push it a bit it begins to hesitate. This continues until it no longer will go at all. It pretty much acts the same at that point as our first post. Only it just completely dies instead of staying on as before.

The first few times you try to start it it starts and sputters out quickly. One time it stayed on but as soon as I put it in drive and went to take off it reacted the same way again.

The best I could do to check the things you mentioned was, check for spark, which was fine. Then check the gas pressure under the hood. We had checked this before and it had plenty. This time it just trickled out. Leading me to believe the fuel pump may be the issue.

As I tried to keep it started in the driveway it did start up almost normal at one point. It stayed on for about a minute. I noticed two things, one it let out a bit of a cloud of smoke when it first started. Second after it died out I noticed a very faint hissing noise which Icould not pinpoint the origin. It lasted maybe twenty seconds. Not a noise that I had ever heard before.

My neighbor and I were thinking about dropping the whole exhaust system and seeing if it still has the same problem to rule out the catalytic converter. However that leaves the car without the oxygen sensors plugged in so I am not sure the car will even operate that way.

The other option would be to just replace the fuel pump but again would hate to put out another 100 dollars just to see if that is the problem.

As for your other suggestions, wire harnesses and the engine coolant temperature sensor. With the wire harnesses there are so many I am not sure were to start. The sensor is only like 30 dollars so if it is worth trying we could probably do that. I am pretty sure it is the sensor in the top left side of the engine. In looking at the sensor it has hardened white stuff on the showing threads, and looks as if it has never been replaced. Not sure if that means anything, or how to tell if it is not working.

The only other thing is the check engine light did not come on at all. My neighbor did erase the codes last time he used his scannner, but I was expecting the light to come on again.

Symptoms indicates it is related to the fuel pump so we can forgo the others for now. We need to get the fue pressure up first. CHECKING FUEL PUMP 1.Turn ignition off. Disconnect fuel pump relay. For fuel pump relay location, See Fig. 51. Using scan tool in voltmeter mode, check voltage on fuel pump relay connector fused ignition switch output circuit. See Fig. 35. If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open fused ignition switch output circuit. 2.Install a substitute relay. Attempt to start engine. If engine does not start, go to next step. If engine started, replace fuel pump relay. 3.Reinstall original fuel pump relay. Disconnect fuel pump harness connector, Inside Trunk On Left Side, Near Base Of Shock Tower. Turn ignition on. Using scan tool, actuate ASD fuel system. Using scan tool in voltmeter mode, check voltage of fuel pump relay output circuit at fuel pump connector (harness side). If voltage is more than 10 volts, go to next step. If voltage is 10 volts or less, repair open fuel pump relay output circuit. 4.Turn ignition off. Using scan tool in ohmmeter mode, check resistance of fuel pump ground circuit at fuel pump connector (harness side) Black/Light Green wire. If resistance is less than 5 ohms, replace fuel pump. If resistance is 5 ohms or more, repair open fuel pump ground circuit.

Checked all of that. The last step was the one step that went wrong. At the wire harness the ground was between 6 and 7. We are not sure how to fix this.

While we checked that we took a look at some other things as well. First off we tried to get the car to turn over, unlike before it wouldn't turn over at all. We then decided to check the gas pressure. This time it actually seemed to have plenty of pressure in the line. We wondered if maybe it was the injectors, so we put the meter on the ones we could get to. They seem to be working. When we turned the key we could hear the fuel pump turning on faintly.

Don't really get why it won't turn over at all today. Would think it would continue to do the same thing as before. ????FRUSTRATING!!!!!!!!

We called a couple local repair shops to see about getting the car looked at. They all want around 60 dollars just to diagnose the problem. Some asked a bit about what was wrong. Only one really offered up his opinion of what may be wrong.

He said that when the crank shaft position sensor and or the throttle position sensor go bad they can cause the catalytic converter to get clogged up. Of course these were two of the first issues we thought we had, and have replaced those sensors. Him saying this though has me back to thinking we should drop the exhaust system to rule that out as a problem.

I am still not sure if the car is going to run without the oxygen sensors though. From what Ihave read the oxygen sensors tell the car how much fuel the engine needs to run properly. Knowing that I would thiink they are necessary for it to run.

He also went on to say that he doubts the fuel filter has ever been changed. This has been another thought of mine. This along with what we found following your help about the ground circuit relay, are other things high on my list of things that may be wrong. The mechanic said if the fuel filter needs to be change it could cause gas pressure to weaken during driving and cause it to stall the way it has. He said along with the ground issue being a possible culprit.

All of the places we called had one thing in common that it could get pricey which for us now even the 60 dollars for diagnoses is. Hopefully we can find a way to address these three possible issues on our own. Luckily my neighbor has some know how and tools including welding if needed on the exhaust. So that will be big help if we have to get to that point.

If you could let us know about the ground circuit repair that would be one less possiblility. That would leave the other two and possibly replacing the oxygen sensors if needed if we are still having problems.

Unless I am missing something I think we may be getting close to the solution. Hopefully!

If the ground circuit has 6 or 7 ohms, that means the grounding point is either loose or contaminated. Check the grounding point at center of deck lid opening, I am not sure where that is.

When you mentioned it won't turn over, does that mean it is cranking and not firing up or not even cranking at all?

Did you check for sparks?

We will try to figure out the grounding issue. That doesn't sound too hard.

As far as the car turning over I am meaning the engine running. It had been running for at least a few seconds. We just ckecked for spark and it was fine. Shortly after we checked the spark is when it stopped turning over. We will have to check that again once we take care of the ground issue.

Do you think dropping the exhaust to try to rule out those possible issues would be worth doing? Would it run without the oxygen sensors?

Yes, engine would run without exhaust but since you have fond some problem, get those checked first.

Regarding the ground, use another wire and splice it to the ground wire and find a sutable grounding point to test if it works.

So we finally gave in and took it to a shop. Although they seemed to have further complicated our problem. According to them the timing belt needs to be replaced, along with the water pump. He said if we don't replace the water pump it will probably go bad shortly after we replace the timing belt.

They said that until this is fixed they really can't diagnose the car. In getting the car to the shop the check engine light came back on, as we got the car to turn over for a bit. We actually got it turn over by pouring a little gas in the carb, making me think more about a fuel pressure problem. When we got to the shop he put his OBD II scanner on and it came up that the throttle position sensor voltage was too high. He said that when he checked that the wire harness was loose due to it not having the little locking piece, so he secured it.

They wanted 570 parts and labor. We priced out the parts on our own and they came to 145. My neighbor said it is not an easy job but that he knew how to do it and would help with it to save us the money. So I guess that is our next step, though Istill need to do something about the fuel pump ground circuit.

Hopefully this will get us somewhere with it. After the timing belt and fixing the ground Iplan to drop the exhaust to rule all of that out if necessary. If we still haven't figured it out we may take it back to the shop to have it diagnosed, though we have already paid $25 and they want $35 more to diagnose it further. Hopefully they will still do that after we do the belt and pump on our own. Wish I had become a mechanic long ago, money seems to be coming in even in this bad economy.

Yes, seems the fuel pump is the cause of the no start. Get the fuel pump ground circuit secured and retest.

Once the fuel problem is resolved and engine is running, you might not need to bother about the exhaust.

I wanted to retire as a mechanic and change to another job but never got the chance. Not being a mechanic is not a loss. If you think it is a good source of income, you are wrong, or maybe I am doing it wrong?

If you require any info on the timing belt job, let me know.
