Hello, one thing in advance: yesterday I used the search all day, but unfortunately I am as smart as before. That’s why I created a new thread out of my despair, because I still can’t narrow down what my Omega (2.0, 16V, 100kw, BJ 1995, X20XEV) could have. Yesterday’s research day here in the forum led me to the following possible causes. – Petrol pump – Ignition cable – Ignition plug – Ignition coil – NWS – KWS – Drosselkklappe But let’s get to the concrete problem: I The car ran perfectly, except some start problems in the cold months. Then at the beginning of March 2009 there were first problems with the gas giving. At full throttle, e.g. during the overtaking, there was only a jerking down then the performance fell. From then on followed days, on which the Omi had nothing and ran perfectly, and then there were days, on which the car suddenly could not even bring more than 2000 or 3000 revolutions power, in idle everything I called the ADAC 4 times! 1. ADAC visit – suggestion to change LMM. LMM changed, but now the car didn’t start. 2. ADAC visit – error code read out. Nothing found. Then the fuses checked. Those of the gasoline pump replaced. Car jumped again. The next but no more 3. ADAC visit – error code read out – gasoline pump relays replaced. Car jumped again, but to the surprise it was like before the replacement of all parts. 4. ADAC visit – car MKL lights up – read out error code, yet nothing found – car towed with the recommendation to replace the throttle flap. 5. car in workshop, read out error code, found nothing. car ran faultlessly again. contacts sprayed on and that was it. In addition, the recommendation to replace the NWS, because the insulation shows a slight crack On last Saturday I picked up the car from the workshop, it ran faultlessly. On Sunday it jumped sc hon again bad and the jerking was back again – even in idle mode nothing went more than 2000 revolutions. Yesterday, however, it started immediately and it ran again impeccable. I am really desperate. Does anyone have an idea? The strangest thing is that you can already make out at the start whether it is going well or not. Thank you in advance for the help Markus
