Firing order, coil terminal locations. Code 301 misfire #1

[quote:7132952d6c="jcelegante"]dodge intrepid, 1996, 137,000 miles, 3.5L engine,
I have replaced spark plugs, and wires. Replace TPS from a different problem. Confusion from different sources of coil terminal locations. It appears that the 3.3L engine diagram is the closes fit.[/quote:7132952d6c]

Re: Firing order, coil terminal locations. Code 301 misfire #1 PO301 no.1 cyl. misfiring is it still popping? could be caused by the following:

Plugs and Wires are they OEM oarts

Weak coil pack for that cylinder, loss of compression-burn exhaust valve- vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), dirty fuel injectors, low fuel pressure, or even bad fuel

Have been looking for that for the last 10mins. couldn't find it, am I dumb or am missing something

Clearly not a dumb a$$...wise maybe :wink:

Engine Performance/Specifications....Fig 1

Thank You I'll make sure that this is how I have them. This is much clearer than the Haynes manual. The confusion I had was looking at it flat on the paper and then flipping it 90' :arrow: as it is on the side of my engine.

I'll insert a picture tommorow it will help show what I'm talking about.

To clarify,
Is this for the 3.5 iter and not the 3.3 liter engine?
Or are they both the same?

Also thanks for the additional Ideas.
This might be the real issue :D

:shock: I didn't even know I had a response. I find it difficult to check. I actually found this by selecting "view my posts."

There was nothing listed in my in box or a reply sent to my e-mail.

I guess I'm still learning How to use your site. :o

Thanks again.

I believe they are the same based on the info I have. Don't feel bad about learning the site, so are we :roll:

These are 4 pictures of the coil terminal From passenger side:

From front of vehicle.

See how the coil terminals are down on the side of the engine. It is somewhat dificult to read diagrams that are one dimentional. My car was running very rough last night. I almost didn't make it home from work. I switched these I put the even numbers on top and the odds on the bottom. :?: This seems to work the best! :D This car is so messed up! :? :idea: I noticed ealier the question about OEM parts. Well, yes and no. Yes I have Champion spark plugs specefied in my manual. But my wires aren't OEM. :oops: I thought they were good. I bought them at Auto Zone. :oops: Not the cheapest and not the most expensive set they had.

I have tried to give votes and points to both of you.

It doesn't seem to work.

It says error why give zero points.

I only have .6 points. I try to give more and it says I don't have enough points.

If I try to give a decimal amount, it says it only accepts integers.

I don't know how this whole thing works.

I don't know when to send a Private Message or Just post it.

I do appreciate all the help given me.

John, Don't worry about the points and all that BS, focus on the car. Our system has some serious defects in it. You appreciate it and that's fine for me. Back to the car:

IF my info is right and my interpretation is right, this is how it should work. The top three are 3-1-5 cylinders. On the engine, the number 5 cylinder is on the passenger side closest to the firewall, then comes #3 and the front one is the #1 cylinder. Keep in mind what Jesses said:"Weak coil pack for that cylinder, loss of compression-burn exhaust valve- vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), dirty fuel injectors, low fuel pressure, or even bad fuel" IF the routing is right, and code is still there and the wires are on tight and the plug is gapped right, then we need to change directions. And if this proves true, pull the plug on the misfiring cylinder, take a pc and up load it. When you put it back in, move it to another cylinder and put that cylinders plug in the number one cylinder. IF the mis-fires moves to the other cylinder, we have a bad plug. IF the mis fire stays on number one, well pick up there.

THANK YOU!!! :!:
For the exact picture. This is what needs to be in the manual.

But...It :D

Now is running very rough. I don't dare Drive it like this. I changed the wires to exactly what you had shown. I then started the car. It was shaking and... I don't know quite how to describe it.

Shouuld I make a direct swap between the bottom and the top. I'm at work. I need to drive this car home tonight. :shock:

I swapped the top for the bottom directly it still was rough. So I swapped 6 & 2. It seemed to run better. Something is still not right.

You can either clear thecodes, run the engine and pull the codes from the computer to find out where the mis-fire is. OR pull on plug wire at a time with the engine running and see if there is a perceptible difference, if none then you have a cylinder that is misfiring.

If so, put a sparktester on that wire and see if there is no spark. If you have spark, pressure test the cylinder.

You going to cause more damage by running it as unburned fuel may be getting into the crankcase...smell the oil and check the level. If fuel is present get the oil otta there. I'll see what I can dig up to help.

On my way home the car was running rough. I stopped and switched the odds back to the top and all in the same order that the diagram showed. It then ran so rough that I could hardly start it. If I put in drive it would die. I swapped 3 with 5 and 6 with 2. It ran very well. But on the highway around about 70 mph it really stated cutting out. I again am not sure where to go with this. I should at least change my fuel filter. I am thinking that I should find a car like mine and see how its sparkplug wires are set. Well I thought I should add that info. before I go to bed.

where is the firing order for a 2011 dodge charger v6
