1991 560 SEL Runs rough cold.


Asked by Oct 11, 2013 at 09:14 PM

Question type: Maintenance & Repair

When I first start it runs for about one second and then dies.  After maybe 5 seconds of
cranking it will start but run very rough and sometimes even die, until it reaches operating
temp at which time it runs perfect.  Runs like a dream as long as temp is 80 +.

1 Answer


cold start valve possibly.
