I honestly don't know the answer but I'll bet you'll find it if you do a search here and read up on all the similar problems experienced by other M103 owners. I'm still trying to completely figure my 88 300E's problems. I've got my 88 about 75% back to good now.

Please post your outcome.
Regards, Eric
