    So what happened ???

    Did you get your car fixed ??

    Sorry that I haven't replied back yet.
    They only think I have done so far, other than the things I mentioned all ready was swapped a coil.

    I know a lot of people posted thinking that was the issue I was experiencing, but I had a feeling that it was something else, and sadly, I was correct, as I still have the problem.

    It will be warm for the next few days, and I am furloughed at my job, so I plan on putting in new plugs, and swapping out wires with old ones I have. Hopefully it will be that easy, but I am worried that it is something else.

    If that doesn't work, I will try to make my way to my garage (25-30 minutes away) and start trying the other things mentioned.

    I really worried that this is the problem, and I really didn't want to spend the money to get a timing belt kit, plus I have never done a timing belt before, so I am unsure about how that will go.

    Yes, a minor update.

    I needed to do the P5's Maryland emission test, which is going to be due soon. I am not worried about passing, as there are no CEL on, but I was worried about getting there and back.

    I wanted to do the plugs before I went to rule them out. With the weather being cold again, and my schedule, I didn't get a chance to do it until the day I planned to taking my car for the emissions test.

    I got plugs, installed them very quickly, and then attempted to start the motor. Normally, I would do an ECU reset after the plug change, but I could not do that this time due to the test, as it would fail because of the ECU reset.

    The motor started, but stalled about 5 second later, I had a hard time to get the motor to turn over after that.

    I got it running, and was going to let it warm up (it had been 3ish weeks since the last time I started it), so I went inside for 5 minutes. Came out, and it was stalled. It wouldn't start after that.

    I decided at that point to reset the ECU, considering I only had a short time before the test station was going to close.

    A short time later, I started it, it ran for 10 seconds, then stalled, I started it again and it ran rough. I noticed that this is common after a ECU reset.

    I took it for a short test drive after the motor reached op temp, and it drove perfectly fine. Sometime soon, I will take it for a long test to see if the plugs fixed the issue. I really, really, really hope that this was the issue.

    Also, let me say a couple things that were said previously, incase someone missed it.

    The plugs I recently removed were not old plugs, they had about 1-2k miles on them.
    I replaced both coils again in the past few months. The old ones were about a year old.
    The problem does not show symptoms until about 5-15 miles of driving. I am able to take short trips with no issues what so ever.


    I have a garage that is about 25 minutes from my home, but I ran out of heating oil, and it is crazy cold there. I plan on fixing that soon, and getting the P5 there to do some more tests.

    I have given it some thought, and I am probably going to replace the timing belt and tensioner sometime soon.
