My accelerator stuck while I was in traffic. I was going 55mph and slowed to 30 due to traffic. When I slowed the engine reved. I turned off the engine after putting the car in neutral. I turned the car back on and it kept reving. I turned off the engine again and it reset. I had the cruise control on but not engaged. I took the car into the local Toyota service center and they checked out the car and told me they could find nothing. That was 9/28/2005.
