Oheneba Posted September 2, 2011 Share Posted September 2, 2011 Hi good Fellows, Im having frequent stalling problems with my '99 ES 300 especially in the mornings and after the car is parked for awhile. The CEL/Trac OFF code indicates its the Idle Air Control Valve (IACV) malfunction. This valve has been cleaned in the past and a local mechanic told me a welded pin in the valve appers to be broken so that replacement rather than cleaning is the best option. Quotes from local mechanics in the Kitchener-Waterloo-Toronto area however, are outrageously high and in the range of $ 700-800 Cdn. I find the part online for about $180-250. The problem is I dont know the exact part to buy since the ones I have seen either have 2 or 3 hoses. Anyone knows the part number and type of IACV for this year model? The production year on my car is 01/1999 Thanks in advance for your help!!! :) Quote Link to comment Share on other sites More sharing options...
Mike B. Posted September 2, 2011 Share Posted September 2, 2011 Go to www.rockauto.com, I believe they average about $150. Quote Link to comment Share on other sites More sharing options...
TA in KC Posted September 4, 2011 Share Posted September 4, 2011 There are 2 different part numbers based on the production year of your car. Based on yours, the correct part number appears to be 22270‑20050. Quote Link to comment Share on other sites More sharing options...
Oheneba Posted September 8, 2011 Author Share Posted September 8, 2011 Thanks Mike and TA for your suggestions. I ordered the IACV (SIAC280 by standard motor) and the gasket by AirTex Wells. Both are scheduled to arrive today. Cant wait to fix this embarrasing stalling probplem. Thanks once again folks Quote Link to comment Share on other sites More sharing options...
