View Full Version : Reving when car Is idling

07-19-2010, 09:16 PM
My e36 just started doing this. It runs fine when I'm driving but when I'm at a light or come to a stop and idle the RPM reves to 2000 or even more at times.

What's the cause of this and how do I resolve it? Any input is appreciated

Does the rpm fluctuate or is it at a steady rate?

Its at a steady rate... It doesn't stall or anything. It just reves up to 2000 or more at times. And when I'm driving it's fine.

Idle control valve or vacum leak.
