Bad or Dirty Air Bypass Valve???
My car runs fine on the road, but after a while of driving at consistant speeds (highway), when I pull off at a light or whatever, the engine is revving at 1500-1750 rpm. If I shut the engine off, the idle goes back to normal.
Is this the IAB valve, and if so, should I clean it out? Any help will be appreciated. Has anyone else had this problem?
Mike
