My coils went bad in my 92 325i @ 160k.. they started shorting out.. usually pretty consistently when starting on hills or quick starts.. At first I thought O2, then Throttle Position Sensor.. On occassion, I would see the check engine light come on for an instant when the engine was "stalling" under load. It got worse over about 5k, until the car became unpredictable. Replaced all 6 coils myself for $300 + $15 for plugs.. It didn't matter whether the car was warm or cool... the idle was fine, & the hwy driving was fine... just the hills & starts from red lights.. Don't know if I helped you any or not..

: Hello,

: I just read the archives regarding ignition coil problems and I am not sure if mine are going bad.

: I have a '92 325i w/89k miles. When the car is running cool (5 - 10 minutes into driving) the car SOMETIMES has a very slight hesitation (kinda like turbo lag in a turdo charged car) between the 1-3 rpm range (a/c off). When the car is warm it doesn't happen or I just don't notice it. Other than the hesitation, the car idles and runs very smoothly. What do you guys think? Is it the coils, do I need a tune-up, what????

: Thanks!
