I, at 110,000 miles, have a new shortblock in my ES300 and the Lexus dealership remachined and cleaned the rest of my engine of sludge, I had them replace the idlers, water pump, belts, plugs, therm, etc.... Then I get a check engine light with no symptoms, take it back in for a check and then they replace the A/F sensor Bank 2. Then I get an idle problem. The sedan used to start no problem, then began to die when I started it, sometimes once, sometimes twice, but eventually starts. No other idle problems that I am aware of.
My question is...when Lexus replaced the short block and cleaned everything related up, do they clean the IACV and the throttle body? They tell me I need a new IACV and it costs $700-750 dollars :o , so I am not happy because I just spent $418 on the new sensor (Air Fuel Sensor Bank 2)) they replaced and then told me I may need another soon, because one fails the other is soon to follow. Maybe it was the IAVC then too? So anyway, if I can clean the IACV and TB and make good with my idle issue, I want to. And how much does it typically cost to have someone clean the IACV and I guess the TB while they are in there and replace the gasket between them?
And one more thing...I get a clicking in my steering wheel when I turn after they replaced my short block, they said it was a knuckle that did not warrant being replaced at this time but the sound would not go away unless it was replaced. The noise was from the intermediate shaft and the intermediate shaft U joint was lubed...was this related to the work they did when they replaced the short block and do I have anything to worry about safety wise?
Thanks!
