My Jeep isn't too bad with the IAC. It revs to 1500 and settles right back down on startup (when cold, about 1200 when warm). I think my coolant temp sensor is reading too warm though, as it doesn't do the 900 rpm cold idle that it's supposed to unless it's below 30* when I start it. If I fire it up on a 60* morning, it drops right to normal curb idle (and yes, the IAC works).
