1988 300e
 

Recently I have been having a problem with my 1988 300e.It starts properly on the first try, but after 15 minutes of running, or even if in park position for 15 minutes, the engine will start shaking and eventually stall. It will not restart, until a while later, usually the next day. Any ideas!! Thanks in advance

First thing I would try is pull the EHA connector off - see if running changes. Might be open loop and rich.
