Hello, now the A-Ware spins around… Of all places I need it.. It runs well in itself, but has dropouts with increasing frequency. Even in thrust mode, you can see how the rev counter drops by 500 turns, but there is no rupture and the real speed does not fluctuate of course. Also no light or anything. On normal drive, the whole thing then turns out to be incl.. The schematic is indeed from the cadett http://www.vectra16v.com/slp/slp_kadett_e_mj87.p But df should be the right one for the 4.2 motronics. What would be the most likely thing now? Crankshaft sensor or ignition coil or STG or…? MKL doesn’t come… The dropouts are also very short, under a second I would say. But the engine feels completely out and is immediately resuscitated…
