If its idle hunting then you need to go through the idle re learn process. Or go into the etc. then to Idle/Rev then set the top idle to 1000 which is idle under load (ac mostly or lights) and 800-900 on the lower Idle setting. Then adjust the IAC to sit around that area.

The power fc is really touchy about idle learn process. Also check to ensure your TB is staying open some.
