My RPM's bounce between 800 and 1100 while in park with the A/C running. My research says that it's the Idle Air control (IAC) Valve. However, it seems the (IAC) is Built into the Throttle Body. Has anyone solved this problem by changing the Throttle Body?

I just noticed mine doing this the other day. I wonder if the throttle body just needs a good cleaning.
