Alloutpc17 Posted March 5, 2012 Report Share Posted March 5, 2012 sounds like the Idle Validation Switch isn't working. does your pedal have 2 switches or 1? 2 switch pedals= 1 TPS and 1 IVS. 1 switch pedals are a combo switch. IVS is a simple off/on switch. if it drops out the truck will return to idle no matter the pedal position. check your harness and contacts. some folks have had success cleaning the switches with contact cleaner. me not so much. I've replace my pedal 3-4 times. one OEM and one NAPA. I just keep a spare with me now. its a simple 10 min deal. Link to comment Share on other sites More sharing options...
Alloutpc17 Posted March 5, 2012 Report Share Posted March 5, 2012 Or try the throttle position sensor, or Mass air flow unit if the both I.V.S is good. Link to comment Share on other sites More sharing options...

KISS_Racing Posted March 5, 2012 Report Share Posted March 5, 2012 Make sure its full of oil first YEP!!!!! Possible bad ICP. Clogged (Gelled) Filter. If truck is chipped, Chip may be going bad. Not sure about a mass air on an 2001. <shrug> Link to comment Share on other sites More sharing options...
