Hello, I have a 1999 RX300 that won't idle and needs IACV replaced or cleaned. The dealer has given me a price of $700 to replace it. How can I know if it needs to be replaced or just cleaned? Also, is this an expensive part or is it just all the time the repair takes that makes this so expensive? Do you know the best way to handle this and not spend more money than I need to? Thanks a lot.
Ok is the check engine light on?
