i dont think its a problem when it drops down and revs itself back up at idle. mine does it sometimes... its usually around 600 rpm, but when i turn my headlights on and radio n shiz on, it drops and revs itself up again...im thinking its normal

I'm guessing it has something to do with your idle control valve. Other posters have suggested cleaning it off. I had similar problem and sprayed b-12(like gumout) on the springs and such...seems to have minimized the problem.

<span style='color:green'>1994 325i </span>- - - 75,000 mi.
No mods - - - very happy as is!
<span style='color:green'>1995 525i </span>- - - 154,000 mi.
No squeaks or rattles... unreal!

thanks frank. Do you think brake cleaner would work well on this type of thing?
