hello so the engine dies every now and then when I start a cross and then it no longer jumps on (so not immediately) when I try to start in dan tukert he so shortly before jumping on (full gas) is then so on 100 u/min. and smokes black out.. I try again and so about 5 min he jumps again as nothing who! changed parts: Ignition coil Ignition distributor knock sensor air meter.. empty running regulator changed the parts because he stammered under driving and has te drop off at 3000 u/min and in empty run always up and down with the drezahl 800-1200 u/min now he is just dying away … does someone know what that is or did you already have it yourself?
