Lot's of "hesitation" and "misfires" in the forum but so many possibilities. What a world. Anyway, just noticed what I would describe as slight hesitation when slightly accelerating then it goes away. No hesitation when on the gas in any gear. No CEL. Also, notice when doing about 60 or so and I let off the gas I feel a hesitation....almost like a "bump, bump." A little like motor mounts loose. I'm going to replace fuel filter....but I read about coils, plugs, pumps....is it injectors? Transmission??? (please no!)
