In the mornings or night if my truck hasnt been driven all day, when i get in it and start it you would think it was carburated. It revs up and down and sounds weak for about a min., almost like its haveing problems stayin running then its fine. ANy idea? I know its a bad descripion but if ya need more info just let me know....

 

Sounds like the IAC sensor-Idle Air Control. Through time carbon fron the intake gets cloged on the valve and will stick. unplug the sensor and tap it a few times with like the handle of a scredriver or somethin similar, then plug it back in and start the engine. If that doesnt help, take the sensor off and spray it a few times with some intake cleaner then with a toothbrush(one that you dont use..preferably...heehee) and scrub it.
Hope this helps.

 

where is that located, in the TB? I know the TPS is there but.....dont know......
