Hi folks!
I don't have a BMW- a friend of mine does however, and her car's idle is screwed up: it wanders up 5 or 6 hundred rpm at idle and drops down, repeating endlessly.
I told her I'd see what I could find out.....anyone here have suggestions on where I should start? She has no shop manual YET! And as I said I have no experience with BMW quirks.
Not much for you to go on to try and help, but any leads will be more than I have now!
Thanks.
