Nissan pickup idling at 1400rpm
Never had any real problem with the truck and still sounds and runs great but just recently it has been idling at around 1400 rpm instead of around 800. Since I have replaced the Pcv vavle and cleaned entire intake manifold and could not find a vacuum leak or gasket leak. Thinking about cleaning out the IAC valve next, would it make any difference? And if so is there anything specific I need to know about cleaning it out other than just to take it off clean it up and put it back? Oxygen sensors were replaced recently as well as coolant temp sensor, thanks.
