I'd add that the idle will generally hang if the idle-bleed screw is run further out than about 2 turns from seated. Most folks leave the bleed somewhere under that threshold and then do the procedure as Jason and Joel have outlined.
There is also a mod where people put a restrictor in front of the IAC. I think the big threads about it were some years back by R.J.
