One problem related to car throttle stuck has been reported for the 2000 Chevrolet Silverado. The most recently reported issues are listed below.
My wife was driving the vehicle. She stopped at a red light, in rush hour traffic, in the rain. Upon accelerating from the light, the throttle suddenly became stuck wide open. She pushed the clutch, took the truck out of gear and managed to pull safely to the side of the road. The cause of the incident, was the air deflector in the throttle body. It broke off and fell into the throttle, wedging it open. Dealer blamed poor maintenance, using premium gas in the truck, and told her to "drive the t out of it" the way it is. The truck has always had all scheduled maintenance as recommended in the owners manual.
