I have a few problems with my ABH recently, which I briefly describe to you, what I have already controlled and what I have noticed. I know there are several "empty running/acceleration problem threads" but I wanted to find a specific answer to my problems.
Problem:
As soon as the engine is warm (nothing can be felt in cold engine), i.e. ==References== 1.8-2.0Bar(according to the treasure ice) runs very restless in idle mode and the speed fluctuates strongly between 750-900u/min and pops out of the exhaust. "bubbling" he occasionally out very loud. However, this is not continuous, but rather as if the engine had ignition oscillations.
A restless wave-like/stuttering acceleration can also be felt while driving.
What did I do?
Sooo, LLRV I cleaned and no improvement, Ignition distributors including distribution caps and ignition cables should also be new (at least they are not the first). From the Lambda probe I once pulled off the single-pole plug (which was not properly fixed under the other one) and measured. There, the values moved between 0.2V-0.9V... but this stutter/unquiet idle occurred again and the values dropped to 0.0V....
Then I put the plug back on and it ran without any problems, even with a warm engine. Short test drive went very positive and I thought the problem was fixed....until I got into the city traffic and various narrow roads (turn off, bumpy plains, stop'n'go etc.) and now the problem was back.
Now my thought is whether it could be due to the single-pole plug, since it is also interrupted with a terminal (fixed) and this possibly. can send no continuous values?!
Do you have another idea? What else could I do? Any temp.sensor/sensor that sends/gets wrong signals when the engine is warm?
I ordered new spark plugs and a replacement LLRV.
I thank you for your help, Vllt. we can do it together...
