Occasionally about 5 or 6 times and counting when initially applying the brake at either 45mph or 10 mph my 1997 Chevy S10 vehicle starts to accelerate with my foot off the gas and cruise control off at what appeared to be full speed/throttle. My first reaction was to brake even harder, but then the antilock brakes kicked in and seemed to reduce the stopping force by not letting the wheels lock. The vehicle continued to accelerate until I placed the car in neutral and then the vehicle stopped and also stopped accelerating.

Intermittently while driving vehicle will accelerate to 50 mph and stay at 50 mph without pressing the pedal, which cannot slowdown vehicle unless making a complete stop. This may cause a crash. Been to dealer 5 times, but could not determine the cause. Engine stall while driving and the vehicle would not restart due to coil wire failure.

Pieces of thottle body broke off and went into engine, ruining cylinder/piston #5. dealer claims that someone broke it off. My machanic states that there is no evidence other than it snapping off.

Engine accelerates on it's own, 1100 to 2200 RPM, must shut off to correct

The engine fails to return to idle when throttle is released. Occurs when humidity is high and temperature is at least moderate. More prone to occur while air conditioning is in use. Engine RPM has hung at up to 2000 RPM. I have been able to travel at 35 mph for 1/2 mile or more without depressing the throttle. This occurred on level roads and the cruise control was not engaged or even on. I have been in contact with another individual, via the web, who had the same year/model truck with the same problem. This is a safety problem. If this occurred when the roads were slippery and accident would be likely. The dealer was worthless. When I contacted GM's website, I got a call back, but I'm convinced that the only purpose of the website is to deadend such complaints.
