1500 RPM Idle

[92BIRD]

My car is back together and runs great, its so smooth it almost feels foreign, but anyways, I was wonder who here knows how to adjust the idle on a 1992 Tbird with a 5.0... Any tips would be great, also, the throttle lever near the tv cable (which does have a new grommet, thanks to PDQ transmissions) it never actually hits the stop, its sitting off the stop... any help? If I did a piss poor job of explaining let me know an ill try to do better.
