'89 200 stumbles off the line?

[Larry C Leung]

Vacuum leak? (I usually recall more stalling than stumble, but I had that
too.) Check the Michelin Man hose (try compressing it like an accordian
and listening/feeling for leaks. Means the palm to hose seals should be
very good), check for oil under the intercooler (if there is some, then
check the IC tanks), valve cover gasket, etc. Try the dipstick test
described in SJM's site. If anything leaks, replace/repair accordingly.
