For some time now I have had some problems with my combination, or much more with the ABB machine installed in it (80 Avant, 2.0E, 115PS, EZ 06/1993). Everything started with sporadic jerking at the beginning of the year. At first only when accelerating, shortly later even in thrust operation. I changed the relay 30 at that time, which caused the problem to be gone for the time being… When it was jerking again after a few weeks, I changed the hose piece on the valve of the crankcase ventilation, because it was totally bloated and added. I thoroughly flushed the valve can itself. Then it was quiet…. until this morning! However, this time I have a much more critical problem: the engine is no longer on its way! I can press the gas pedal on the floor plate, but the colleague ABK trembles a little bit in the empty run. After that, I already lost a little bit of speed, but no breath of power. I was allowed to park and wait three times until the Zicke has recovered again? But now I have no suspicion of this change?
