Problems with new donors...

Hello, everybody! call me back from a longer learning-related abstinence and I have to ask about questions...

I'm really desperate... last week my old master (89er 3.6l Automat) started to "spuck around" some of the time. i.e. he started stuttering around and at the ampel he sporadicly went out... short and good to the garageist and the memory read out... diagnosis: speed encoder and air volume sensor (ot encoder was released before approx. (two months).

the parts have been nicely replaced... I then joyfully in the best mood to the garagist to pick up my favorite and then a "tolles" conversation with the mechanic... "he's still jerking! but in the error memory there is nothing! I should simply add an additive to clean the injection system, then it will be again"... I'M NOT A WORD!

Now it is the case that the speedometer (and also audible from the motor) at deep tours (approx. ==References====External links== 50 km/h) with constant gas fluctuating back and forth... and at higher speeds (motorway) it "sacks" with lightest gas removal... If I give a little gas again, then he comes back; but with a jerk! ==References====External links==*Official website 800, now approx. 600)...

And then he went out at the traffic light again... what I still noticed is that the petrol pump is causing a hell of a noise (but it has been like this for years and therefore not really in my checklist); but: until now, the "surrender" has been constant, while it is now irregular (e.g. when changing from R to D, the buzzing seems to fall short to rise again immediately).

please, please, please, if someone has an idea of how to help my darling...

Greetings from the beautiful Üchtland
