Hello friends, I had already opened a similar thread but unfortunately the tips didn’t use anything. Since I had all the important seals on my Coupe renewed it runs so quietly in the stand that you almost didn’t take it. Overall: Ignition cable with distributor cap and candles new ignition distributor and ignition coil all rubber hoses which are relevant for the injection or the engine are complete KE 3 Jetronik from an accident car with control unit My problem is still that in my opinion it still does not go as it should. I had it on a performance test stand and there it was found that it lacks 10 HP. I thought because of the age it could be but there was the Audimechatronician quite different opinion. He says he has to bring it and these engines go as well as never broken. He pulls the first 4 gears as he should up to the beginning red area only when it goes to the despeed then he listens to just behind 5000 tours to turn on. The Tacho then stands at 205 KM/H. He has Tüv and Asu without any faults. I would have heard a few opinions.
