Hello, I am currently having problems with my Audi80 (type 89), year 89, with the 2.0E machine (engine 3A, 113hp, KE-Jetronic). If the car has been warmed up and you switch to thrust mode (e.g. roll down a mountain without gas) or the car is in the lead at the traffic light, the engine is slicing smoothly ahead of you. The speed then varies by +/- 100 rpm. There is no running calmness! You notice clearly that there is any controller or sensor in the control. As soon as you give gas everything is i. O.. The power is right, I have also found no problems with gas acceptance or speeding up. The only thing I have noticed are smaller leaks in the exhaust. Can this disturb the Lamba control so? Or does the push-off spin? Or is it something completely different? In advance thank you for your help. Greetings Jan
