Does a coil go bad when it gets hot. Runs fine for awhile then starts to miss. After about 8 miles. What cause coils to go bad is it the heat. I checked the ohms, they all read .04 or .05. Think my wires could be at fault. Thanks RAN
There was a recall on the coil back then.
The coils get hair line cracks in them and then arc to ground. Pull off the cover and start the car in the dark and notice the blue light show around all the coils. All the ones on my 92 325i were like this when I bought it, even though they ohm tested fine, the car missed a lot. Replaced and it was fine.
Did you replace all 6 of them Todd? Just curious...

Yes, I did replace all six. Even though one of them had been replaced about a year before I bought the car and wasn't bad. The other five were still original and arcing alot.
