anyone have this problem. when the truck is cold i start it and it dies. if i start it wuth my foot on the gas and keep the rpm up it will not die. once it warms up it idles fine. this is happening to me about 30% of the time. i am think it is is the throttle position sensor but i am not sure. any input?

 

I have the same prob. Mine started right after I installed my Airaid. Going to remove it this weekend and see if it goes back to normal.

Seems like these Air Control Valves are sticking on hundreds of trucks all over the place. I thought it might be weather related but, maybe it's just buildup.
