Stop using your a/c, easy...

Maybe you should turn up the idle speed a bit... Where is it idling warm?

Check/clean your IAC valve. It is supposed to compensate, at idle, for the A/C and the extra drag it causes.

It has to do with the tune. Mine used to do the same thing after I did my cam swap. Tuning took care of the issue.
