I was driving the vehicle. As I started up a hill the speed limit changed. I gave the gas pedal a little push. It went to the floor where it stuck wide open. The car leaped forward and I immediately applied the brake. I really had to push the brake as hard as I could to get the vehicle to stop. When I got the vehicle to stop I knocked the gear shift out of drive into neutral. The engine was idling really rough but then it smoothed out. I did not crash the car and continued driving with no further problems. The vehicle has 64,875 miles on it and this is the first this has happened.
