I was driving around 40-45 and applied a small amount of pedal to get around someone who was half off the road, and all of a sudden the truck just took off and threw me back in the seat! I searched for the gas pedal with my foot and couldn't find it, until I looked and it was smashed on the floor. I pounded on the pedal with my foot to no avail, and pumped the crap out of the brakes and while I was doing that the pedal suddenly came back off the floor and the engine quit revving at top rpm's.
Totally freaked me out! Anyone else heard of this? Truck is in for service.
