One problem related to car throttle sticking has been reported for the 1997 Chevrolet Astro. The most recently reported issues are listed below.
Hasn't been anything more than a nuisiance so far, but we believe it could be a safety issue. The gas pedal sticks, especially right after starting the engine. Starting off in a controllable manner is almost impossible. Reliable Chevrolet in tulsa replaced the throttle body assembly once under warranty at about 40,000 miles, and now the problem is starting again. As the problem gets worse, it starts to happen more often, I. E. Even after the van has been running for a while instead of just after starting. The gas pedal just sticks when the throttle is closed. It takes quite a bit of pressure to unstick it, and when it finally moves, it opens the throttle more than intended, and the van starts off in leaps and spurts instead of gradually and gracefully.
