86560SEL - The ICV is located at the front of the engine. You unplug the ICV while the engine's running.

I am curious to know also, because I also have the exact same problem with my 91 420SEL stalling immediately when put in gear from P or N. The problem has only started recently in two different occasions. I thought it was weird at first when it happened. I restarted the car, put in gear and stalled again. The third time, it was fine and drove away.

I do not have the problem stalling while driving like others have experienced in many of the searched threads. Maybe this is the beginning of something worse waiting to happen to me??..

I checked the ICV by unplugging and the idle shot up to 1500RPM so I think the ICV is fine. I do not have the problem restarting. It starts right up after stalling.

I've spents the last couple days searching this site and other Mercedes forums of the related problem. I've read so many threads and this is the only one close to what I am experiencing.

Anybody else has any ideas why it stalls when put into gear from P or N?

THANKS
