I've been on the road with the V8 for a few weeks and I noticed the following:
At vollast, so kickdown I feel a strange slight jerking from about 4,000 revolutions. It's kind of a wave-like acceleration.
I have renewed the following parts in the last 6 months:
- Lambda probe
- Tap sensor (brown)
- OT and speed encoders
There's nothing in the bugstore. Taped on the reverberator first, but it should be deposited. The only suspect is the green knock sensor, the cable has become a bit brittle, but plugs are fine. I'd like to change it, but if it's a dirty job, I'd hate to do it.
I drove again tonight and it was better then again. I can't feel it anymore. The engine was of course always running warm and warm. Hot.

In any case, I thank you for every tip! It may have been the same. similar problem.
greetings
Daniel
