I was pulling a windy hill in fourth slowing down to make the curves and then speeding back up some. I had close to a cord of very wet freshly cut firewood. When I noticed that when I dipped below 1500 rpm and started accelerating again the truck would stutter two or three times at around 1350 to 1425 rpm then be fine. It did this once in third but not in any other gears however it was not until it was flat that I could test the 5th and 6th.

Was the stutter caused because I the truck was in such a low rpm with a heavy load or is something going out on me.

Thanks Rob
