idle air control valve appears to be causing stalling issues on 2001 Lexus ES300

The car had been stalling on the 2nd or 3rd use of the day lately, never the first startup in the morning. Lately it stalls at just about every traffic light. Car has 127,000 miles. How much and who can clean this or replace.

Were you able to get this issue resolved? Was it the idle control valve that was causing the stalling?
