1.8T 2000 GLX - here's some recent history;
March 2013 - Drove to work and cylinder 1 completely died, I felt it die when I shifted from fourth to fifth going up a not too steep hill, was not firing at all. Bought a new Ignition Coil for 25$, slapped it in, car ran perfect. I also replaced all four spark plugs later that day since they were due for a changing.
Two weeks later on the way to work, same thing, up another hill in fifth cylinder 1 stops firing again. I moved the Ignition Coil from cylinder 4 to cylinder 1 and vice versa - lo and behold the code the car throws now is cylinder 4 misfiring. Went back to PepBoys and they gave me a replacement which I put into cylinder 4 and car ran great. (Cylinder 1 still working like a champ with the OE Igintion Coil that used to be in Cyl4.)
So I just assumed that the Coil that the store had sold me was wonky as the 2nd replacement worked for a few weeks.
Over the course of those few weeks I did the timing belt/water pump with my friend (thanks to D2Beetle for that awesome DIY, was a hell of a job but that belt is on there perfectly.
) and that was pretty much all the work done on the car.
Driving home one night last week on the highway in 5th gear at around 60 MPH the car suddenly shudders and loses a bit of speed, same feeling as when my coil originally died but no CEL or anything and the car is still running fine. After I get off the highway the car feels fine although it's just lacking power in the top end. Got another new coil, everything back to perfection.
That coil worked good for a few days until I noticed that in fifth it would start to lack power up hills. Replaced that coil with another and it's running fine again.
So after all of that and a few wasted Ignition Coils later, it sounds like there might be some faulty wiring somewhere?
Not sure what else would be causing repeated failures like this?
What doesn't make sense to me is why is cylinder one fine and dandy right now when it's the one that originally failed and the recurring failures are only with these replacement coils?
Any ideas anyone? I'd like to get this settled as the car is mechanically very good but it's getting unreliable when it's trying to make me drive it on three cylinders. >_<
