SOMETIMES WHEN I DRIVE MY TRUCK WHILE I'M DRIVING THE TRUCK BEGINS TO STUTTER WHILE I'M PRESSING ON THE GAS PETAL LIGHTLY. NOW IF IT DOES THIS I PRESS THE GAS A LITTLE HARDER AND THE STUTTERING GOES AWAY. WHAT DOES THIS MEAN?

Hi:
My first guess would be a weak or bad coil pack. Have the computer scanned to see if there is a code. Most nationally recognized parts stores will do it for free. If they find a code, "Random Misfire Cyl..." replace both the coil pack and the plug.

Does it feel/sound as if you were driving over small caution bumps on the side of the road? You may want change the transmission fluid. I had a similar problem with an 05 Expedition, had the fluid changed and the problem went away.
