To add to what revamp said, if you get the car good and warmed up then unplug the IAC, it should idle at 750 rpm. If not, first check again for vacuum leaks and then turn that screw on the throttle body until it idles at the proper RPM. Then shut it off, plug the IAC back in, and it should be at around 1000.
