Won't start unless Check engine light is on.

Cleaned the TB and replaced the IAC with a mopar one. Still have high idle. I will start and idle at 900 to 1000 when cold. Then as it warms up it will climb to 1200-1300. When I put the tranny in drive, it seems to idle around 800-900. If I shut off the truck when it's warm and restart it then it's at 1000 again for a few seconds and returns to the 1200. I have been checking over all the vacuum lines but don't see anything bad. Runs really good except for that. Starting to frustrate me.
