Engine Performance problem
1986 Audi 5000 All Wheel Drive Manual 200000 miles
I have an 86 5000 TQ that is hesitating under acceleration. When engine is cold after first starting it drives good for about 2 minutes, then as the engine warms up it starts hesitating badlly when accelerating. Seems to run a little better when at higher temps, but never like it should. Have done new O2 sensor, checked for vacuum leaks, etc. Have taken the car to 2 different Audi "specialists" and they can't diagnose the problem. Anyone have an idea of where to start or what to do here? Any advice would help, seems like a fuel problem, but I have had some minor electrical issues as well. Don't know if that is playing a factor here. This is an intermittent problem, as every once in a while during a drive it will perform properly until I shut it off again.
have the same problem?
