Hello all, I have strange engine problems with my b4 2.0e ABK. ́94 The following Symthome: Cold start everything ok as soon as I get it at operating temperature is slightly gas give up to approx. 2000-2500U/min (in stand), it turns up, but falls (without changing the DK position ) again to approx. empty speed and then again high to 2000-3000u/min and that as long as I give gas. When I then give more gas he shoots into the air filter box. Engine power is equal to zero. Idle under all Sau When I pull off the LMM plug the problem is gone. (I haven’t done a road test yet if it has performance but I don’t think especially there emergency run ) I once plugged in the LMM from my convertible that worked very well up to now –> problem back there, plug off–> emergency run–> problem away petrol pump runs (although a little rough ) even if the engine speed sucks off voltage also remains the same. Fuel filter is new. Spark plugs, cable,distributor new. Control times and zzp tuning I have now excluded the relay no. 30 because it does not jerk but totally shits.But will it exchange the days for sure. Injection nozzles I exclude also sometimes because it runs in emergency run great petrol pressure regulator falls out thus also the only thing I could imagine now still last: ECU in the Ar** vll. Lamda or DkPoti ?! is slowly but surely a little ingenuity / perplexed as I go the most meaningful or even further n should. greet max
