Totally stock car besides the boost leaks. What is stock base idle on these cars? I'm idling at about 2,000 right now which I'm sure isn't right.
Thanks

Check VFAQ /ubbthreads/images/graemlins/wink.gif It's a little more involved. Not much, but a little /ubbthreads/images/graemlins/smile.gif

Ground the timing plug, and ground the diagnostic pin (or hook up you logger)and then set to the desired RPM. This sets the ISC to a set value .

Your Base Idle Set Screw (BISS) O-ring is probably shot, causing the high idle.

Quoting Charles:

Yeah, that's probably all it is. /ubbthreads/images/graemlins/hsugh.gif /ubbthreads/images/graemlins/rofl.gif

It could be any number of things that include vacuum leaks, idle switch, FIAV, ISC, etc. Not just the BISS. Check them all.
