Two problems related to accelerator stuck have been reported for the 1996 Chevrolet Blazer. The most recently reported issues are listed below.
At 30 mph accelerator pedal got stuck, consumer applied more pressure and pedal went to the floor. Then, got stuck in that position. Consumer had to apply brakes hard, shifted to neutral, and shut off engine. Dealer stated the engine was damaged, and had to be replaced.
Accelerator pedal sticks in idle position. It seems to be worse the first time the pedal is pressed after the engine is first started. However, since 5 months have elapsed since the problem was first noticed, it seems to stick now almost every time the pedal goes back to the idle position. It feels as though something is holding the accelerator in the idle position, as if it is snagged on something. After you apply extra force to overcome the sticking, it travels smoothly with no other snagging. A CO-worker owns a 1997 Blazer and is having the same problem. I have driven at least 2 different company vehicles which were 1998 and 1999 model gm minivans with a similar sticking accelerator. All of these vehicles, including mine, stick only in the idle position. The problem results in the driver having to use excessive force to accelerate from a stop and thus it is difficult to keep from gunning the engine when starting from a stop.
