    ok the problem happens around the beginning of the video

    what all that happens

    -lights dim
    -motor feels like it wants to shut off
    -and the idle is rough
    -it also pisses me off

    does your truck hesitate at all when you slam the gas?

    What ryan said. try cleaning it. head up to the auto store and grab a can of throttle body cleaner and clean your TB out real good and your IAC. i would even clean my MAF sensor too but not with the same cleaner! MAF cleaner will do the trick.
