This is for my 92 300D 2.5 turbo. For a year now, my car has this intermittant problem. Just after starting the car and backing out of the parking spot, the car will stall and you have to restart.

After the restart everything is fine. Sometimes after pulling out and putting in drive it will stall. This used to happen very very rarely, now its more frequent than before.

Where do I start troubleshooting an intermittant problem like this? Thanks in advance.

P.S. sometimes in stop and go driving on the free way at low speeds (like 3 mph or something) after i let off the accelerator it will stall and i have to put in neutral and restart.
