I would try a complete throttle body cleaning, IE, taking it completely off the truck and spraying it down with a good cleaner. You'd be suprised by the amount of gunk on the back side of the throttle plate. To get the full benefit from this, have both battery terminals disconnected while you do this. I did mine for a slight stumble off the line, seemed to help. I didnot however disconnect the battery terminals.....which I will be doing tomorrow, they prolly need cleaned too anyway. It's worth a try, it's easy, & you're only out the price you pay for the cleaner.
