I have a 2001 F-150. Recently when I was driving it, I noticed at speeds of around 25-30 mph, I didn't even have to put my foot on the gas to keep it going.
Kind of like cruise control at low speeds. Then when I stopped and put the vehicle in park, the idle went really high, around 2000 rpm. Would that be the IAC that is faulty,
or could it be something else?
