I have a 1983 240D. Rebuilt engine 10k ago. Just changed the injector pump and injectors. Also did a valve job, and the transmission fluid is good. Ran fine one day and bad the next. Started with the car dieing when it gets put into gear. Sounded like there was not enough rpm's to keep it going. Then it started dieing when I stopped the car while in gear, ie. stop signs. Started playing with the idle adjuster but that did not help. It ended up getting worse. Now it won't get into gear without dieing no matter how much I rev it up. I know there is vacuum leaks in the car doors. Today I got the car to idle by holding the linkage up what I thought was a very high amount but it was at a low idle. I kept it at the same position for a while and without warning the car revved up a lot. To the amount I believe right for the position of the linkage. so I lowered the linkage and the car almost died, then I put the linkage back where it was and it went back to idling at its low idle for a while then revved up again. any suggestions?
