the check engine soon light on?

You need to have the computer scanned to identify where the problem is coming from.

Let me know what you find.

The check engine soon light went out on it's own. I have lubed the throttle linkage and so far it runs well and no light. guy paris

Thais good news. Let me know if it happens again. If the check engine light comes on again, try to get it to a nationally recognized parts store to have them scan it while it is on. Most parts stores will scan it for free, and it should identify where the problem is coming from.

Let me know if you have other questions.

My 96 Sable wagons CEL came on, so I went to Auto Zone to have the code checked. They told me it was the O2 Sensor after the catalitic converter, bank #1. I purchased a new Bosch O2 sensor fromthem and they told me to disconnect the battery and then change it, code will reset. I did that and after 19 miles the CEL came on again. I am assuming the "new" O2 sensor is not defective. Do I need to have the CEL "reset" some other way???
Thanks!

Go back and get the code read again. If it's the same ask to get paid to replace it again if it's defective, or ask for another guess.
If it is not the same then post what code you get.

There may be an evap code now present since that monitor can not run without the first code being addressed.

The service light will not go off despite the fact that it came on prior to the usual 5000km service schedule and when checked, the oil, radiator fluid, transmission fluid and brake fluid were at their correct levels. The car runs well and makes no noise.
The garage ran a check and were uncertain of the cause. They were able to switch the light off but it has come on again and has switched off for a short period and has returned again.
The car mechanic says that there is nothing to stop us from driving the car as it runs well but we are concerned about that light.
I should be grateful if you can help solve the problem.
Thank you in anticipation,

Hi Bryan,

Have you had the codes read since it came back on? If not go by your local parts store and have them scan it for you. Most will do it free. If have any codes write them down and post.

I have a check engine light on, not all the time. When it is on the transmission is not shifting right. I can only get up to 45mph at 3000rpm. What can this be?

The first thing i need from you is the exact codes your computer has that is are starting point.

I've tried to pull the code and it wont show. I did it by jumping the eec under the hood like it showed me on the computer and the light goes off.

Have you tried a analog volt meter instead of watch the light?Meaning a volt meter with a needle not digital.

No I don't have one of those. The attached image is how I did it. I used a jumper wire instead of a test light.

Looks like.your going to have to try a different way or you may to just get a scanner that will read your car.If the lights coming on and its acting up we need to start with what codes it has.

What kind of different way that I can try because I don't have a scanner, and I've been trying to pull the code all day, I know the code is what I need. I really need to get this car going because it's my only way to work. It started doing this yesterday. Thank you for your help.

Here are the ways i have listed to retrive codes analog volt meter scanner check engine light and star series tester.

Thank you, I will try to contact a buddy that might have one of those. I will get back with you and let you now the code.

Your welcome keep me posted best thing you could get is a obd1 scanner that would work on your car.

I also have a 1995 Mercury Sable that I'm desperatley trying to get back on the road. I got insurance and tag on it and broke the next day. Check engine light comes on after running a few minutes and runs bad with black smoke coming out of tail pipe. It seems like it's not shifting right. It will only do 45mph at 3000rpms. I tried to pull the code with a friends scanner and it wont pull. I've tried jumping the eec and using the scanner. My friends scanner is a snap on with right adaptor and computer card.

Maybe a problem with vss, vehicle speed sensor. I'll find a diagram.

Thank you for everything

The vehicle speed sensor is lower right rear of engine. Could be other issues? Don't know why you can't communicate with computer?

would the vss cause the black smoke out of tale pipe when reving the engine?

I don't know? Can effect shift patterns. Sounds like it is flooding, not sure why? How long since over-all tune-up?

a month ago. just changed plugs, wires, dist.cap and rotor button

For the diagnostics, where did you hook-up?

The ecc conection under the hood left side towards fire wall. Here's how i tried to jump it.

That hook-up looks good to me.

It's still not showing me a code. When i hook it up this way the check engine light stays on. That's why i got my friends scanner and it still did'nt show anything.

There maybe a problem with your computer, or the wiring circuit?

How do i check that?

Check voltage and grounds at the computer. My pin-outs show the sti connector to have 5 volts on it?

Sorry i'm not sure what you meen about pin-outs or sti. Where is the computer located on that car?

The sti is in your diagram. For the 3.0 the computer is under the hood, passenger side, close to firewall.

Thank you, by the time i got to your response it got dark. I'll have to check it tomorrow. With no light it's a little difficult.

I understand. Let us know.

Hi, i have a 1991 Merc Sable LS with 122,000 miles. I've had a bunch of problems with it since i've had it, brakes, radiator, alternator, all of which have been taken care of. Recently, I filled up the overflow tank with antifreeze because i was going on a trip and i felt like it was a good idea. Car drove fine during the trip up, and on the way back a couple days later, while getting gas i noticed the car was leaking antifreeze. I had to go home at that moment, so i drove home carefully watching the heat. Since then the car has had absolutely no problem overheating so i figured it was just the overflow tank because of that. However, recently the check engine light has been coming off and on, and the rpm's while seeming a bit more "normal" than usual are not normal for my car. While in park it is now idling at 1000 rpms rather than the normal 2000 and it just feels wierd while it is shifting. The car has always grabbed while shifting so i normally don't think anything of it, but it feels different, and it is coupled with antifreeze leaks and the check engine light. The car drives like a dream on the highway but city driving is like a nightmare. I'm taking it to the mechanic on thursday, but i'm nervous and really don't want to wait till then to figure out what it is.
please help!!

First of all, the car used to idle at 2,000rpms? That's not normal, that's really high. If you've been having problems, the first thing to do would be to have the car scanned for trouble codes. That will narrow down the problem. Also, have you looked at the radiator hoses and around the water pump to try to find where the coolant is leaking? It may be someting simple that you can fix yourself.
