My Rx300 has exact same problem, so I got read the forum and took out the 2 air intake hoses and the IACV locates right under them. I took out the two screws and cleaned the inside with the throttle body cleaner. The problem went away, so here is the pictures I took (IACV is the black piece with the two screws, one of them has the yellow dot on it).
Hope this help somebody in the future.
I cleaned the Throttle Body and IACV as directed and even went as far as cleaning the Mass Air Sensor, however my 2000 RX300 is still having the same idling problem. Any suggestions?
