Good day all and particularly Dick in Danville VT. I grew up on Bennington,
now in Houston.
More to the point of rough idle. My '90 Coupe US Spec 100K has had a
slightly rough idle for almost 3 years from 80K. Some days it is worse than
others and some days it is almost perfect. The Houston dealership Star
Motor Cars has mechanic that has been there for over 25 years and told me
that he has experienced this condition on the 560's very early on even at
60,000 miles and as little as two or three years old. He produced from his
tool box a drill bit of about 16"L X.1/4 inch in dia. This, he told me, is
the solution to your problem, but I need to break down your engine to clean
out some air passages in the block relating to your exhaust. I wish I could
recall more specifically his description but by the time we got to that part
of the conversation by mind was clouded by dollar signs spinning out of
control. Can you imagine the cost of an MB dealer breaking down your
engine.? There is no "mis-underestimating " that bill. When I asked this
mechanic what did "new" owners do when they complained about this rough idle
and the car was out of warranty, he said "they just lived with it".
My indy MB mechanic, who is great and very prudent with his customers money,
told me to just live with it also or give him a months salary and he'd
probably be able to figure it out. On the other hand, a Houston '89 Coupe
owner and forgive me if you are reading this as I may , probably, have your
name wrong Ron or Rod Wood had the same problem (discussed at the Coupe
Picnic in Memorial park about 3 years ago) took his coupe to a Shell station
that has a mechanic on the staff that apparently works wonders with all
kinds of high end cars and found his rough idle very quickly at a very low
cost. When I've taken my car there it is never idling roughly so he cannot
help me without leaving the car for days.
Long way to get to the question. Other than problems like bad heads or
blocks, has anyone else experienced this on again, off again rough idle and
found a solution? I would like to think it is a vacuum leak where maybe a
hose moves with heat or cold or engine movement but I or no one else can
find one.Some days it drives me crazy at every red light.
Any suggestions would be appreciated.
