It's under where the throttle cam is. You use a Torx 15 to adjust it.

Why do you want to raise your idle?

Idle speed is controlled by the PCM, not by a set-screw adjustment.

I want to raise it just a bit so when I tap the gas the the car doesn't do a nose dive in rpm and sometimes stall on me. I am running a stock LS1 computer with a LS6 crate engine. The car runs great and idles at 500 rpm with no tell tell signs that I have an LS6. The car sounds stock but when i am stopped and I tap the gas the rpm goes up then it goes way down and will comeback up but sometimes it dies like I said.

Actually on a F-body idle still can be changed a few hunder rpm with the throttle stop. Yeah so just turn the screw clockwise a little bit until you get it right.

Or send me your TB and I'll port it and I'll raise the idle for you.

hey Bret I am sending you a PM to discus $$. I know Steve Frank in Houston who is a close friend and I have seen him install cams and help him change the idle by the screw but it wans't a 02 model. I just want to make sure that it can be done. He is off at reserve training right now and I hope he don't get shipped off! I know I can call Thunder Racing and get a ported TB from them for a bill. Let's discuss this issue further. Any references?

Idle speed is controlled by IAC, not a set screw. The PCM is in control now. You have to change your idle speed with a keyboard not a torx wrench.

Default 02 Thottle Body Question

Is there a Idle screw on the TB? Is it on the back side of it where you need to pull the TB off the car? I want to raise my idle only a few hundred rpm.

It's just like drilling a hole in the TB blade. It also gives the TPS a high reading so it will raise the idle speed.
