Rough Idle Issue?

Sometimes I have a rough idle, sometimes not.
When the idle is rough, I turn on the AC, and the idle smoothes out.
Could this be an AIC issue?
What else could be the problem?

It could. You could try removing the IAC and cleaning it, and the passage for the IAC. I would also check for vacuum leaks. How many miles do you have, and when was it tuned up last?

195,xxx miles.
I bought it 2 months ago. The idle was fine until just recently. Everything else runs great. Starts right up. Haven't tuned it up yet.
