While driving on the highway i decided to pass the vehicle in front of me. At the same time i had hit the button to resume the speed i had set on the cruise control. I pushed the pedal all the way to the floor to quickly pass the vehicle in front and when i got past him and let off the peddle my vehicle kept accelerating. I tried turning off the cruise control but that didn’t help. I finally put the car in neutral and coasted to a stop with the engine racing. I tried to pull the accelerator up thinking it was stuck but that didn’t work. Finally i turned the vesicle off and restarted the car and it started working normally. I don’t know what/why that happened and i’ve been afraid to try to duplicate that incident by pushing the accelerator all the way down again. I think this is dangerous and thus i’m reporting this.
