Approx 37,000 miles on truck. Only mods-K & N filter.
About 2 weeks ago I started noticing a slight hesitation on take-off---I use 2nd gear. Also slight smoke on take-off which I didn't have before without a load or uphill. Runs great other than that. Possibly also slight smoke on initial pedal use from the other gears. Changed fuel filter. Pump appears to be working fine(do not have FP gauge), but yesterday when changing filter, it seemed a little louder.
Any ideas???
