I have a problem with my 735i 12/1990.
When I start the engine, it first runs calmly, after 1-2 minutes in automatic position D the car starts to swing up and down with the rear (when the brake is down). The engine saws. With warm engine this problem does not occur, only in a completely determined period. I also think the acceleration occurs to misfire. Sometimes the engine does not take the gas correctly on. What could it be??
