Motor AEC runs slightly idle

Hey
After I finally found time to switch my 6 gear and fix the problem of unclean idleness, here's my resume.

-Intake spider resealed
-LLRV exchanged / and also cleaned
-Distributor caps both new
-Injection valves from Yener sealed and cleaned
-Zündkabel tested all in order
-Benzine pressure regulator replaced
- Underpressure hoses tested and partly renewed
-Cylinders run all with any case, every exhausting cracker is hot

It is still running as before.In idle mode it is easier to run round so that the hood (opened) is slightly waxed and exhaust can be heard from time to time small misignitions.

I unscrewed all 8 spark plugs (Bosch 4 electrode) and looked at the candle picture.Slight deposits aif all so bright white above all the last two of the driver side (if you stand in front of the car)
I don't know if they were changed when the engine changed but that would be my next step.

Do you have any ideas?

Aso and fault memory sets off as error at and at intake air tempers. otherwise not.But the same in green
