I've researched everything this site has to offer, and nothing is the same as this problem.
91 tsi awd. 5 spd
car runs like a dream at first start up, ie.) mornings, leaving home for work. drives great to my destination. but.. if I go to restart the car within lets say about 4 hours (depending on temp outside) the car runs like crap with a misfire. first thing I did was pull the wires while car was running to test for resistance build up to cause the misfire. cylinder 1,2, and 4 arc at the coil. I bought a new coil thinking the coils were breaking down. Coil did not fix it. So I tried wires thinking that the wires were building so much resistance that the coils couldnt build enough current. Wires did not fix it.
the timing is good, the plugs are 6's, the fuel is good, the ecu is recently rebuilt. when its misfiring, I can drive it down the road, just feels like a dead cylinder while driving. When its idling, it sounds more like a miss, the motor is rocking but you can def hear the miss through the exhaust.
I'm going to through a new set of 6's in it tomorrow for giggles.
I'm wanting to know what yall think? again.. this only acts up once I TURN CAR OFF. I can drive it 15mins, or 1 hour, doesnt happen till car is off, runs fine once its cooled off enough I guess. So tells me resistance building up, but why only when car is turned off??
thanks guys, and the compression is 148-152 on all 4. coolant gauge works, car does not overheat, and there are no boost leaks. car runs on 8psi. and runs like a dream on 1st startup.
