Hello, I’ve already used the search function and tried all sorts of things that have been written, but I’m now with my Latin at the end. Anyway, this is about the following: I changed both cylinder heads then because of defective valve shaft guide. I then immediately made the crackers and timing belts with water pump. Lief also really good. But he started to run round at some point in the stand. Now the symptoms are that when I stand at the traffic light and have it on “D” the car wupps a I would always give a little bit of gas. If you are standing on the exhaust you can also hear it running round. Is not a synchronous drone but as if it is always after the idle. If I have it on “P” or “N”, it is so that it is also running quite unevenly. Have already made like out of the search function: – Kws swapped – Nws swapped – LLR swapped and cleaned – throttle flap cleaned – candles cleaned – new ignition cable When you drive everything is wonderful, no performance verl Maybe somebody else knows something.
