I have 86 420SEL(130k mi)that start to have rough idle when hot.When the engine is cold(first start in the morning) runs ok.After engine warms up to operating temp. engine start to shake badly at idle,especially after depressing accel.pedal few times or after driving;ok at higher rpm(over 1000),drives ok.
I would appreciate any suggestion,
Mil .
