Hello, I hope you can help me – I don’t know any more at the moment. Saved a 850 2.0l 10 V from the scrap press. Now he has been TÜV for 2 weeks and now he doesn’t want to turn off anymore and shows a lot of power loss. A few days ago he ran his 205 to Tacho on the highway without mucking. At first he just didn’t go over 140/150 km/h but turned out in the stand. Meanwhile, himself has been uncoupled somewhere, fluctuating between 4,000 and 5,000 end Here he only jerks. In addition, after a few seconds smoke rises up in the area under the battery history: motorized before Tüv: candles,distributor finger/cap,LuFi, oil/filter change, thermostat LuFiKasten exchanged (was for a long time warm air), thermostat cooler, battery as said after that everything is good. Then power drop and no turning out anymore. Then: flame screen cleaned( hardly dirty), throttle flap cleaned, ignition cable set, petrol filter, no fault in the memory so far without success and it gets worse every day?
