Ok, my 2.5 in. cat back has caused my idle speed to drop...sooooo im gonna raise it back up...
How to adjust IACV -

Warm the engine up to operating temp.
Turn off the engine.
Disconnect the TPS.
Start the engine and adjust the idle speed using the stop screw on the throttle body to 650 RPM's.
Turn off the engine.
Reconnect the TPS and restart the engine.

If the IACV is working correctly your idle should be correct. If it's a bit low, try adjusting the screw on the IACV bypass to get your idle speed to ~700 in neutral with no load. (no load means no lights or A/C)

I know thats how u do it but I cant FIND the screw, and HOW much exactly do I turn it?

How can you not find the screw? It's right above where the throttle cables attach to the TB.

It's the red-backed bolt/screw in this picture. Near the throttle cables. Viewed from driver side fender.

Get the idle speed down that way, and if it's not perfect, then use the IACV.

edit, forget about the other arrows...those are pointing to the TPS.

Both the arrows point to the TPS. Use the IACV first, TPS later or not at all.

Yea, I know they do, because I got it from the TPS troubleshooting website. Today, I just noticed that the picture had a good example of where the red-backed throttle body stop screw was located. The faq's call to adjust the TB first, then IACV. Yea, I didn't mean this to have anything to do with the arrows, I just forgot to post that when I attached the picture.
