Toyota Avalon Low Engine Idle and/or Stalling Due to Dirty Idle Air Control Valve

(18 reports)

Debris can get into the idle air control valve. This will restrict the air flow into the engine, causing idle speed and/or stalling when cold. The valve can be cleaned or replaced to correct this concern.
