Ahhhh!!!! What did I do!! TB Help! Alright so I bought a shaner s3 for my car. It does have a larger hole drilled for idle, and I read that would make it idle 3-4 hundred rpm's higher. So I go to test drive it and with the clutch in the car is still at 21 hundred rpm's or so, not good! It won't go back down to a managable range until the car it completely stopped. It will go down to 11 hundred if I shift into say 5th. SO WHAT DID I DO??? THIS ISNY NORMAL IS IT?? I NEED SOME HELP!! Thanks everyone.

If the hole in the TB blade is enlarged, it will cause all the things you described. You need to either fill the hole (JB weld, etc.) and drill a new one to stock size (almost positive 5/32" is the stock hole size) or get another TB blade. You can't get a new TB blade from GM without buying a whole new TB, but I've read in the past that one of the sponsers has extra TB blades in stock for the factory TB. I beleive it was TPiS, maybe try contacting them.....

Agreed don't drill anything on a stock TB. Get another stock one if you can and try that first. Use the idle screw for tuning with proper computer turning to build upon it. If you can't do it just have it professionally done. No use messing with it if you don't know what to do.

Put the stock TB blade back in. Drive it for a little while like that, and after some miles and a few restarts all should be back to normal.

PS. If the idle is still 300rpm higher than the desired idle speed programmed into the PCM, then you will eventually get an SES light for a high idle code. Mine would throw that code once the idle was about 200rpm higher than what the PCM was set for.

A buddy of mine had the same thing happened to him when he put his S2 on his car. I told him to do the idle relearn process and the high idle went away. He didn't even have to mess with the stop screw.

Idle relearn will not fix it completely if the hole is too big. Period. I've been through this.
