It acts as if it stops running for just a fraction of a second and then continues to run, it does this with cruise on or off while cruising at road speed. Sometimes this creates a pretty good jerk and other times this happens much smoother, this can happen several times a day or just once or twice. Any ideas??"now...my predicament...im posting for a friend of mine...i know nothing about nothing lol.He is having kinda the same problem, except his truck never recovered from the hiccup.
