Rough idle / RPM drop when idling in drive
I have a 2002 RX with 130k miles on it. I've noticed lately that when I'm stopped at a traffic light or idling in drive that the car gets a vibration, the RPM drops below 750 and goes up and down. It usually happens once I've driven a little, and turning the AC compressor off sometimes stops it. Is this caused by a dirty IAC valve?

I would tend to agree with your diagnosis.
