The gas pedal would stick and the car would not decelerate when removing pressure from it. This happened a couple of times on separate days but would unstick and decelerate fairly quickly. Then today the gas pedal not only became stuck but it accelerated and I had to hit the brakes to get it to stop accelerating.
