fast idle, is this a sign of problems to come?
i was reading an article about purchasing an SEC, they warned not to ignore a fast idle, because of vacuum pipes and control units.
now i have a W123 200T, which is very different but does suffer from a fast idle that i can't seem to slow down.
could anyone tell me, if this is a problem that needs to be addressed or in the case of my car, not really a problem so much as a nuisance.
thanks in advance, i am always grateful for your help. jb
