2002 Dodge Ram 1500 Base 8 Cyl 4.7L
My 2002 dodge ram 1500 is idling up and down on its own. Any ideas on the issues
? I think it's possibly the TPS
Several possibilities; vacuum hose leak, air intake leak, maybe the throttle position sensor (TPS) or the idle air control (IAC) valve is faulty. Check the vacuum hoses and air intake as first step.
