Moin municipality, now I have to ask again a question which causes me to break my head for a long time – Nobody is perfect. The NG of my big son turns so sluggishly high as if the 2nd stage would be missing. On the other hand, my Quaddi (NG) is a rocket. All vacuum leaks are fixed, ZZP re-set (yes, in diagnostic mode with strobe lamp), new ignition harness incl. distributor cap & fingers as well as candles (NGK), LUFI new, sensors (except Lamda) new. Hope I didn’t forget anything. Oh yes, after the ZZP was set he ran a few days better, then the old condition was announced again. Especially if it is cold and wet outside, he doesn’t like it at all. Until he reaches the operating temperature, he is partly at the jerking, then it is possible … but not right. From 4000 rpm it can also happen when accelerating that he has short full oscillations, but then again “normal” continues. What can I do about the zosses again to the Re. first thanks for tips. LG, Frank
