Idle question?
 
I replaced my friends throttle body and plenium but now the revs are always at 2,000 How can I change were the car idles at? I think he bought a ported and polished ford throttle body. Is there any way to adjust those?

The TB should have an idle set screw on it and it is probably not set correctly. I can give you ionstructions if you need them.

make sure that you hooked up all of the vacuum lines back up... ex... egr, pcv, etc... that would def make a difference... i got t/b, plenum and CAI installed it and didn't have to do any kind of "adjustments" we're not running carburators here its called EFI...just make sure you did it right..

There's still an idle speed set screw. It should be on the backside of the throttle body.
