Coil pack

Hi Kyleh, first it all depends on what size engine you have. That determines how many ignition coils your vehicle has.

Its a v6

There is 6 ignition coils. Does your vehicle have a miss?

Yes. Is there an easy way to test them?

Also has a rough idle and stalls/shuts off when we go to a stop sometimes.

First thing have you checked if you have a engine code?

It says p0304 which I think it was missing on the 4th cylinder if I remember right. I don't know much about cars.

Ok yes that's right it is number 4 cylinder missing. Now we need to find out where number 4 is located, in order to do that I need to know what year is it?

2003

Ok great, when you looking at under the hood and you spot the coils closes to you, you should see only 3 of them. Number 4 is the coil right in the middle of the 3 that you see closes to you. Do you see what I'm talking about?

I'm not by my car now. I'll have to check it tomorrow. I'll get back to you. Thank you

You're welcome Kyleh, I look forward to hearing from you.

Could it possibly be the o2 sensor causing the problem??

just to interject here you have normally 3 coils not 6 on this car each coil feeds two cylinders. best thing to do is to freeze frame on a scan so you can read and see what sensor is screwing up if none are then check fuel pressure and check for a vacuum leak. finally if that is all ok do basic stuff like wire resistance and compression etc.
