Five problems related to accelerator pedal have been reported for the 1997 Chevrolet Astro. The most recently reported issues are listed below.
The vehicle has a problem with developing a condition where the throttle pedal sticks. High pedal effort is required to over come this condition but this practice is unsafe because the result is a rapid acceleration or lurch when the pedal becomes unstuck . Problem is chronic as it has to be addressed at least annually by cleaning the internals of throttle body. The cleaning is successful in removing the problem initially, but the condition always recurs after about a year (10,000 miles) of driving. Although cleaning the throttle body on a regular basis is a recommended maintenance item.
When pulling off from a stop there is a delay in acceleration, the gas pedal will be really hard to press then it will unexpectedly release, causing vehicle to jump forward. Consumer feels this is very dangerous, and can possibly hit someone.
While driving gas pedal went down, and driver had no control engine just revved, and she had to put vehicle in park before it would stop.
When applying the gas pedal the vehicle lurched forward which may cause an accident. Took to dealer, told it was a normal maintenance problem that could be repaired at owner's expense.
When driving the vehicle and taking off, pushed the accelerator it stopped with a kink in it, then pressed a little more, it lurched to get past that point. Dealer contacted and stated they will remedy the problem by spraying the thhrottle.
