94.5 obs no throttle when cold

truck runs great otherwise...when i crank it in the a.m. all it will do is idle, if i hit the gas pedal theres no response and the cel comes on for a second or two. It takes about 3 or 4 times pushing the pedal to get it to rev. I'm thinking one of the two sensors on the pedal...i've heard they can be cleaned with contact cleaner...any thoughts on what might be up here? The truck only does this after setting overnight...once its working it does great all day...even after setting 8 hours or more!

I would try the contact cleaner on the Idle Validation Switch (the two-wire connected part on the pedal assembly) and see if it helps. The switch is open at idle and closed just off idle position if you want to test it. Cheers!
