Bogging Problem on LT1 A4.... HELP!!
It's aN A4, and right when it's ready to shift into 2nd, it bogs bad and wants to die, than comes back to life. Sometimes she dies @ idle too for no reason. Also it I'm @ WOT from about 80 mph, the motor backfires and goes crazy, and won't shift or continue to accelerate.
Maf is fine. I have no exhaust leaks, or induction leaks. Could it be plugs/wires? Vacuum? Optispark? (just replaced opti)
Input more than welcome PLEASE, I'm getting tired of guessing, and scan codes don't reveal anything helpful.
