Report: Idle air control motors may become carboned up at 100,000 miles
Toyota Corolla Problem
The idle air control motors tend to become carboned up at around 100,000 miles and can cause a start and stall and/or stalling at stop sign problems. Our technicians tell us that many times these motors can be cleaned, however, the sure bet is to replace the idle air control motor and clean the throttle body.
