So i made the IAC Gasket, so the revs drop quick..... The revs do drop quick, but now my car at a light is idling at likw 1100rpms... When it use to at like 800. Any ideas?..... i figured it was because i disconnected the iac so the computer would adjust to it, but i drove around for a while and it was still idling at 1100.
 
Check for vacuum leaks would be a good first step...they will cause high idle.

And remember that you did modify the component that makes your car idle in the first place. I know its supposed to "restrict" air, but you never know. You could try just taking that off and see if the idle goes back to normal.
