Do any of you guy's know if you can turn off the high idle feature or lenghten the amount of time before you start the truck and the high idle engages? When its below zero I can only emagine what the oil pressure is in the engine since my gauge never really comes off of being pegged over passed the 80 psi mark. I want to know just for when it is really cold out.

Press the gas 3 times in 5 seconds in the ON position and it will not go to high idle ..untill the next time you start it up.. just plug it in ..ALWAYS and leave it plugged in..
