Your profile shows a 83 300D. Rough idle could come from the valves out of adjustment. When were they adjusted last?

The fuel injector rack also has a part, a small brass piece whose job it is to dampen the rack. These often need replacing on older cars.

Clogged injectors can also contribute to a rough idle .... as well as bent or bad valves, bad fuel injector pumps ..... also a bad engine mount ..... etc.

How many miles?
