Driving on a rural road in extreme cold. Approx 20 mi / hr. Gas pedal stuck to floor. Threw truck in neutral to slow down & by hand reached down to lift the accelerator from the floor. Incident did not happen again that day. Took to dealership & was told that a new accelerator would be installed.

1997 GMC sierra does not decelerate when the accelerator is released. Braking and/or downshifting only increased the rpm. Transmission can be put into neutral then back in the desired gear and the vehicle will then slow down slightly. Service dealer claimed no problem found.
