Just bought the truck never had a problem runs great, little oil leak nothing bad at all, suddenly it starts to rev up like the trottle was stuck, so i cut off the engine then it allows for about 10 min run time before it revs up to 4g's then stalls no matter how much i try to keep the throttle down to give it gas it won't keep it running?

just replaces IAC valve runs better seems when it gets hotter it doesnt run very well still wants to stall

Clean out the idle air control valve and also clean the MAF sensor with approved cleaner and test the throttle position sensor.
