My 99 300M 3.5L V6 for the past few months has occasionally (2 times out
of
30 or so start-ups in a normal week) has a Rough Idle on startups.
Doesn't
happen every time...but when it does happen, it can be felt through the
whole car as a fairly rough running engine.
Today I went on a trip, car sat for about 25 minutes..I get back in and
start it and it's running horrible. It's like it's on 2 cylinders...I
gave
it some gas and it just spitted and sputtered and eventually revved up,
but
never died..after about 10 seconds it cleared up. I backed out of the
drive
and it started to hesitate a little as I took off and then didn't do it
the
rest of the way home.
No check engine lights came on or anything..I'm not sure where to start on
this one...Like I said this is the first time that it actually sounded
like
it might have actually died but didn't..other times have just been a rough
idle that smoothed out over a few seconds.
Any Ideas on what to look for?
Thanks,
Mike
