Omi is making me worry again

MoinMoin first of all , the following problem , My grandma either goes out in the stand gas or the speed rowing like wildly up and down and then the MKL goes on . was already in the Opel workshop of my trust and the supposed LMM change and that problem would be done . I also made . Nuisses so that the problem no longer occurs regularly , but still so 2-3 times daily . If I give at the traffic light some gas ( approx. 1000-1100 rpm ) the MKL goes out in the stand gas but immediately again to o the engine goes off. I can rule out the following, because only this year made or changed. complete ignition system LMM LLS This funny nozzle, which everyone wants to dig up here, has been removed, cleaned etc. Maybe one of you knows further, because the workshop does not work for nothing and I have no ducat ash to stand in the cellar.
