no throttle
 

'04 6.0 . lost throttle this mourning pulling out of my neighborhood. hit the gas and nothing happened. truck did not cut off, just no throttle. I didn't let it warm up for long like I typically do. turned the truck off and restarted and the problem went away. anyone know what would cause this?

Throttle position sensor is possible, would probably throw code. The joys of fly by wire!

ICp sensor is most likely cause, if you have a couple sticky injectors it can happen too.

Thanks guys. Ive also noticed its starting to take a secound to crank when cold, then rough idle untill it is warm. No smoke - white or otherwise.
