My 2002 dodge ram 1500 is idling up and down on its own. Any ideas on the issues

    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.

    Check out the many on-line auto parts sources; such as - www.partsgeek.com or www.rockauto.com - to list just two sources - for the replacement parts, such as the IAC or TPS.
