Hi all, I am a newbie to the forum and to the Mercedes diesel. I just bought a 1983 300D and during the drive home (275 miles) I think I may have lost something in the throttle linkage. At idle the engine stop lever wants to sag towards the valve cover. The lever has a lot of slop in it, so at idle it sags toward the front of the engine and toward the valve cover and causes the car to idle very poorly and in some cases shut off. I can move the lever back to the correct position and the car idles correctly. Moving the lever takes no effort, almost like a spring or bushing is missing . Other than this issue the car runs and drives great. I have attached some springs to the lever as a band aid and it seems to be working, but I would rather fix the issue properly. I have searched for this issue and didn't find anything on it, but if this is something that has been covered please let me know what to search for or attach the link. I attached some pictures to clarify.
