Default lt1 idles high adjustment on throttle???? help

Okay heres the deal I had to remove my intake and remove my throttle cable lines...Im not sure but when I put everything back together and went to start the car it idles high at around 2k rpm and slowly begins to climb... The throttle idle adjustment screw as they would call it ---theres about a half inch space between that and the bracket... i can push the bracket all the way back and it will idle normal... does anyone know how I can fix this problem...

Don't mess with the throttle stop screw. That is NOT how idle is controlled. The IAC controls the idle speed. Can you scan and check your IAC counts? If the car idled fine before you did the work chances are there's a vacuum leak somewhere.
