Lexus ES300 Problem Report
Lexus ES300 Engine Stall or Low Idle Due to Debris in Idle Air Control Valve
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.
