Hello Have brought me an LMM from the scrap yard, which I can bring back again at defective. My question: What must my car do with running engine if I remove the plug from the LMM? How do I recognize a defective or intact LMM with the driving car? Are there measured values? Is there anything to consider before and after installation? I am still testing the misconduct of my engine! If I do not jump in the sun at the first start of the day, shake like a diesel without glowing. iten Start he goes through longer and then starts, still without getting drunk! For the rest of the day no more problems. As long as it is cool and the car is in the shade, he doesn’t show the problem. Only when the sun shines on the car. On the other hand I thought I would have eliminated the barely perceptible jerking during the ride. Think! Ruckles still. Despite everything, the performance, remaining driving age and consumption are right. What have I changed so far: ZEB complete ignition incl. cable, Ke Rzen have 16,000km of oil changes before 16,000km, hardly noticeable oil consumption, no blue smoke, no white smoke from the exhaust, valves I guess therefore not air filter before 16,000km throttle valve cleaned Well-known defective but not yet changed, idler! Only shows itself really in winter when it is cold. Then he saws 4-5 times and then is good. After that runs in the stand round. Many fank for your answers!
