Hello to all, I’ve had a problem with my SL500 (WDB1290671F1, 1994, 146,000km, engine M119, LH-Jetronic, 2 distributors) and hope that among you is a specialist who may have experience with such a problem. The Fzg. has been idle for 2 years (650 !/min) and in increased idleness up to 2000 revolutions light dropouts, i.e. the engine shakes slightly. In cold condition a little more than warm. Under load the engine runs perfectly and has power. It starts cold as well as warm. A MB-Hdl. recommended me to visit a BOSCH service. But he probably had even less idea of the SL than me. He also noticed the shaking, but did not know any remedy and has given me 2 cans system cleaners into the tank. Now I have not renewed the resistor cable – I have already renewed the resistance filter again.
