Idle air control motors may become carboned up at 100,000 miles on Toyota 4Runner

Problem overview

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