1995 Chevrolet Blazer Vehicle speed control Problems

“Two occurrences: car was started when warm, and quickly throttled up to high rpms. Mechanic disconnected electrical connections, and replaced alternator. Six months later, car started normally when warm, and throttled to high rpms after traveling 30 feet, headed toward pedestrians. Applying both brakes stopped the car, but motor continued to throttle, until ignition turned off. Car started normally a minute later, and I parked after driving uneventfully two blocks with hand on ignition key. I'm afraid to drive it again, until diagnosed.”

“The speed control module turned on by itself, and the throttle opened wide. Pressing down on the brake did not release the speed control. I was forced to throw the car into neutral (which red-lined the motor at about 4,500 RPM) and shut it off. Only on the third restart of the motor did the module release. I was traveling at about 50 MPH, and began to accelerate to go up a small hill. The cruise control was not on when this problem occured. The other problem concerns the EGR valve. In late 1999, I took the car to a local Chevrolet dealer because it was running rough. …”

“After having recall's c 98043, c 99046, and 95020 cross 95c31 completed, returning home from the dealer 1/2 mile away, stopped at a traffic light, our Blazer lurched forward and smashed into the rear of the vehicle in front of my wife who was driving. The vehicle had to be towed because of damaged grill,radiator, hood and fenders. Is there a way this incident could have been caused by any of these recall's? Also after the recalls were fixed the dealer had to fix a stuck EGR valve, because the truck ran really bad after the recalls were fixed. …”

“At 2 1/2 years old, my car developed an engine surge problem at start up. This eventually affects braking since the engine will surge when cold and if I'm trying to stop (I.e., the stop sign at the end of my block where kids are waiting for the school bus) and the extra power of the engine surge causes the car to lunge forward and I must apply extra pressure to the brake pedal to stop the car. I have had the car to the dealership over 10 ten times. They initially told me they couldn't find the problem although they could witness the symptoms. …”

“Had problems with engine stalls and occasional surging took car to firestone (auto mechanics) lafter talking with people who had similar problems thought maybe it was bad gas, changed to premium gas and used gas additive. Problem still persisted went to firestone had tune up, injectors cleaned. …”
