1984 500 sel stalling.
I have a 1984 500 sel, 260000 miles, runs fine except that the engine stalls, (or shuts of ) by itself from time to time. It will often restart by itself within about 4 seconds if the car is moving.
If it shuts off while I am stopped at a traffic light I must shut of the ignition and then it easily restarts. My mechanic changed the fuel pump on it and said that would take care of the problem, but it didn't. What else could be causing this problem?
