When my 300D has been run a while the idle is rough and the car sits there shaking and after a long run on the highway it seems to do this more so. Any ideas??
I am wondering if the idle needs to be adjusted or what because when I bring the idle up 100-200 RPM the situation is not so bad. The situation happens when the idle is at 700-750.
BTW, I have recently changed the fuel filters and oil and these have not changed the problem.
Thank you for the help.
