Truck is lagging when trying to accelerate from a stop. I mash the gas and the rpm's slowly climb until about 2100rpm then it wakes up and goes. While cruisinand maintaining the same pedal pressure, the truck gradually slows down until I mash on the gas. Then it down shifts and goes. Rinse and repeat.
