Car Stall Problems of Chevrolet Prizm

The throttle on my car stuck at full or nearly full when I accelerated to pass a vehicle. I firmly depressed and held the brake pedal, then took the following actions: checked that cruise control was not active; checked that nothing was depressing the accelerator; pulled back on the accelerator; while continuing to press the brake pedal moved the shift lever to neutral and turned the ignition switch to acc; pulled off the highway and called for a tow truck. The mechanic at the garage stated that a pin had come off of the throttle assembly, excessive movement caused a daisy chain link to jam in the corner edge of the assembly holding the throttle open. An aftermarket cruise control system installed on the car in 2000 by the dealer was not working for at least two days prior to the incident. The mechanic inserted a cotter pin on the end of the throttle control arm, test drove the car and requested that I drive very little until I could return for a brake check when the garage reopened.

My 2001 Chevrolet Prizm, which has a Toyota engine, stalls when accelerated just after starting. Pumping the pedal a few times gets the car moving again normally. This typically happens after the car has been sitting idle for a while. The local Chevrolet dealer looked at it and said there were no issues. The spark plugs were checked and found to be in good working condition. However, the problem still persists.

The contact owns a 2001 Chevrolet Prizm. The contact stated that the check engine indicator would not stop illuminating on the instrument panel. Whenever the vehicle would approach a stop, it would stall. The dealer and several local repair shops performed a diagnostic, but were unable to find a defect. The vehicle has been experiencing the same failure for the past three years. Recently, the contact drove to a local repair shop and the mechanic stated that the spark plugs and oxygen sensor were defective; however, only the spark plugs were replaced. Immediately following the repairs, the failure recurred. The current mileage was 75,000 and failure mileage was 45,000.

The consumer state his 2001 Chevrolet prism was hesitating and stalling on a cold start. The vehicle was stalling in the mornings when the engine was cold and set overnight. The weather was not an issue with the car. The owner took the vehicle to the dealership for inspection. The owner did have a copy of TSB 1538049 which indicated procedures that could be done to help with vehicle performance. The owners vehicle has only 31,000 miles, and was about 4â½ years old. The owner talked to gm, and they said that what ever it cost to have the vehicle fixed they would use as a credit on the purchase of a new vehicle. The owner had the air filters changed, checked computer for codes, this showed misfires present, replaced spark plugs, cleaned air induction system last year. Recently, in July, the codes were checked again and there was no indication of anything wrong. The repair shop suggested that the owner replace the throttle position sensor. That did not help the vehicle. The owner went back to the dealer, and had a diagnostic test done. The owner was having problems with the experimental suggestion to be done on the car because this will have no guarantee that this will fix the car. The owner was afraid to drive the car because of the hesitation and stalling. The cost of the TSB suggestion will cost several thousands of dollars. There was no warranty left on the car.
