The contact set the cruise control while going up a hill and vehicle sped up.while going down the hill the vehicle just kept going faster. The rpms were above 4000. He pressed on the brake pedal as hard as possible. This slowed the vehicle a little. He managed to pull the vehicle to the side of the road. He got out of the vehicle and opened the hood to checked the throttle assembly. It was stuck. He worked with the throttle and finally managed to get it released. The contact has not taken the vehicle to a dealership to duplicate the problem. Updated 2/7/2006 -

1997 Chevrolet Blazer engine revved to a very high RPM. After the vehicle hit a pothole in the street the engine revved very high. It revved somewhere around 4500 RPM's. the consumer popped to hood to see if he could determine what caused the problem but couldn't find anything wrong. The next day the consumer inspected the vehicle and found that butterfly valve was open and showed where the wedge shaped piece was supposed to be riveted on. It appeared that the wedge piece broke away from the rivets and pivoted down into the throat of the injector body causing the computer to sense the need to floor the gas pedal.

While slowing down from high speeds vehicle will start to accelerate. Also, vehicle will shutdown at times too. Contacted dealer, and dealer has replaced several parts of vehicle, including transmission; but, nothing has worked yet.

Car accelerated to 70mph when I when to downshift to get off a major highway ramp. I pressed on the brake and lost my brakes. I turned off the key to stop. I was traveling on a major highway in Maryland and at that time of day traffic was light. I could have caused a major accident due to this acceleration problem and killed someone or been killed myself. This is a major safety issue that needs to be addressed now!!!!!!!

Cruise control cable/ plastic retainer snapped, cruise control engaged by itself. On approach to an intersection accelerator pedal jammed despite release of foot from pedal. Attempted to brake with both feet on brake pedal with no apparent slowing of vehicle. Given the fact that both of my young children were in the vehicle, and we were quickly approaching the intersection, I put the car in neutral. With both feet on the brake and still no slowing of the vehicle, my concern for the safety of my children became overwhelming. With my engine reving at an audibly 'pending- doom' level, and cars cruising directly across my path, ( crossing traffic did not have a stop sign), I slammed my vehicle into park and prayed for it to stop. I then proceeded to turn off the ignition and it wasn't until an eternity of a second later that the vehicle ceased. The sequence of events that took place, ultimately resulted in the towing of the vehicle, and the replacement of the engine. My biggest concern is for the future safety of the many families who own these SUV's. please contact me.

Throttle sticks open at low speeds this could result in a serious accident. This caused by carbon buildup in air intake throat around thottle control plate.

I reported the problem with my cruise control speeding up two years ago. You failed to respond, confirming that you are in bed with the manufacturers. My cruise control has been in the off position since my first report. While cruise was in off I accidentally hit the middle button on when I tuned on my high beam. The cruise engaged and sped up. Again it wouldn't turn off until I turned the engine off.

I would like to attach this to the previous comment that the front throttle body plates need constant cleaning as well. I would like to also enter a correction that my vehicle does have a ABS brake system

I was driving on the tollway and approximatly 1 mile before the toll, I felt my car accelerating without my foot on the gas. I thought the cruise control was on, but it wasn't.as I approached the toll and had my foot on the brake, my car was not slowing down, I almost crashed into the car ahead of me. I put the car in neutral and shut it off. After putting it in park, I was told by the toll authority to try to start the car. When I did, it revved up all the way into the red zone,8000 rpms. I took the car to the dealer and was told nothing was wrong with it. About 2 weeks later, my engine was deemed ruined. The rod, pistons and bearings were shot, not due to lack of maintanence. The cause of the engine problem was due to the throttle. None of this should of occurred in a car that is still somewhat new. Please respond.
