From rockauto. very impressed with their customer service so far.

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

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!!! :)

I own a 1999 Model ES300 too and i have noticed this week that the engine is getting louder with whistling sound during acceleration on the high ways. The CEL and Trac off light was on for a week and then went off just the day before i was to see my mechanic for diagnosis last week. The light has not come on since then. Everything seem to be fine except for the noise i hear when im accelerating. Im taking it today for check up though

Just bought 1999 es300 for $6500 Cdn with 212k kms taxes and 2yrs engine and tranny warranty inclusive of price. Car had Autocheck score of 89%. Car record shows it was driven for under 1000km from 2006-2009. It was in immaculate condition with all options lexus ever had on that generation of ES300. B) Those who knew what I use to drive before('90 mazda protege LX), now nod their heads when I drive by :D
