I am having an issue that I feel mimics the IAC valve needing cleaning or replaced. However I don't think the 2010 has it if I am correct? Sporadic idling suddenly, mostly with air on. Will idle down , then up and then hold for a bit, then down again.. Stalls a time or two. With throttle it runs perfectly. So Im naturally thinking IAC, but I don't have that so maybe I need the throttle body cleaned. I should mention I bought the car with 120K on it 2 weeks ago. It had been sitting for a year so I put in fresh gas, new rotors, pads and calipers, new battery, new oil change, recharged ac, etc.. and it had been running perfectly until this happened today. We bought it for my Mother N law. Any suggestions greatly appreciated!
