My son is the owner of a Nexia & has a problem with irregular idle speed. The car runs well but will sometimes idle very high for periods even when at normal operating temperature. I have noticed some of the advice on these threads mentioning the IAC valve. Is this the likely problem & if so how do you fix or clean it? Should it be replaced? Thanks for any help that you can give.
