Report: Debris in Idle Air Control Valve May Cause Engine Problems
Lexus RX300 Problem
Model Years Affected: 1999, 2000, 2001, 2002, 2003
Engine Affected: 3.0L V6
Average Mileage: 118,390 mi (50,400 mi - 155,500 mi)
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.

feels like its going to cut off when in idle. Car starts shaking and have to hit the gas to keep it running. Once moving at a decent speed in drive it feels fine.

Would not idle and jumped around at stop lights to the point other drivers would stare at me. High dollar repair shop said it had to be replaced at $600 area. Went on line and saw where some were being cleaned. Went to another shop and they cleaned it overnight. Soaked it in cleaning fluid( build-up of carbon) and had no problems since with that part.

Car wouldn't stay "on". Had to pump the gas pedal just to get it started. Idle valve was replaced; cost me over $800 for part and labor.

idle control needed to be replaced. My car kept idling low and kept stalling. Took it the repair shop and paid $325.00 to get it fixed. Check engine light has come back on though and now it will not start at all. Headed back to the repair shop.

Report #11Visitor, 2003 Lexus RX300, 3.0L V6, 90,000 mi
When cold or warm, try to start the car, the engine immediately stalls. Have to give it gas and hold it at 1,000 rpm for about 10 seconds for it to not stall.
First time had this problem what car was about three years old and still under warranty. Dealer replaced the intake air control valve (part number 22270-20050) and gasket (part number 22215-20010). They tech took 0.9 hour to perform.
Six years later, having problem again. Will try cleaning the IACV.
