I have built in my Cali yes a “new” 16V motor now I drove about 150Km with it without any problems, but just I had it a little bit over 4000U7min and there blib he “hang” at 3000U7min but the gas train did not hang! So he ran with 3000U/min I made the engine with the Zünschlüssel. Then I tried to start what also succeeded, but then when I went from the gas into the “Standgas mode” he went out. That several times! Then I waited a little, then I tried to come to the garage, Everything was ok again! Running so there are no problems, runs also round and so. Only when I come to the stand gas, then at once again 3000 rpm, then I tried to create the rest to Gargae, where he now also stands again…. Presumably the idle turntable or something… What do you think! THX
