CAMPAIGN: CARB. ACCELERATOR PUMP LEVER PIN MAY LOOSEN. Chevrolet El Camino 1980

For 1990-2009 cars

# CAMPAIGN: CARB. ACCELERATOR PUMP LEVER PIN MAY LOOSEN

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type, must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within sixty(60) days after ten- der of a vehicle is prima facie evidence of failure to repair within a reasonable time. If the condition is not adequately repaired within a reasonable time, the owner may be entitled to an identical or reasonably equivalent vehicle at no charge, or to a refund of the purchase price, less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair the vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owners are being instructed to contact the nearest Chevrolet Zone office if their dealer does not remedy the condition within five days of the agreed service date. If the condition is not remedied within a reasonable time, the owners are instructed how to contact the National Highway Traffic Safety Administration.

DEFECT INVOLVED

General Motors has determined that a defect which relates to motor vehicle safety exists in some (1980-1983 Full Size Chevrolet and Malibu Model cars) equipped with closed loop quadrajet carburetors and Police Car Packages. The accelerator pump lever retaining pin may come loose after repeated wide open throttle applications. This could allow the accelerator pump linkage to bind and prevent the throttle from closing. If this were to occur, vehicle speed would remain constant even though the driver has removed his foot from the accelerator pedal. Loss of accelerator control could result in a vehicle crash without prior warning.

Dear Chevrolet Owner:

This notice is sent to you in accordance with requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has determined that a defect which relates to motor vehicle safety exists in some 1980-1983 Full Size Chevrolet and Malibu Model cars equipped with closed loop quadrajet carburetors and Police Car Packages. The accelerator pump lever retaining pin may come loose after repeated wide open throttle applications. This could allo the accelerator pump linkage to bind and prevent the throttle from closing. If this were to occur, vehicle speed would remain constant even though the driver has removed his foot from the accelerator pedal. Loss of accelerator control could result in a vehicle crash without prior warning.

To prevent this from occurring on your vehicle, your Chevrolet Dealer will install a special cotter pin to retain the accelerator pump pin and a spring clip thrust washer on the accelerator pump link. This service will be done at no charge to you.

Instructions for making this correction have been sent to your dealer. Parts will be available approximately August 29, 1983. Please contact your dealer to arrange a service date. The labor time to perform this service is approximately 15 minutes. Please allow additional time for the dealer to process your vehicle.

If this condition occurs prior to the time the service is completed, the driver should shift the transmission to neutral, apply the brakes as necessary, bring the car to a stop out of the line of traffic, and when stopped, turn off the ignition.

Your Chevrolet Dealer is best equipped to obtain parts and provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date and they do not remedy this condition on that date or within five days, we recommend that you contact the nearest Chevrolet Zone Office, either in person or by telephone, for assistance. The Zone Office will assist you and the dealer in getting your vehicle corrected. The locations and phone numbers of the Zone Offices are listed in your Owner's Manual. After contacting your dealer and the Zone Office, if you are still not satisfied that we have done our best to remedy this condition without charge within a reasonable time, you may wish to notify the Administrator, National Highway Traffic Safety Administration, 400 Seventh Street, S.W., Washington, D.C. 20590, or call 800-424-9393 (Washington, D.C. residents use 426-0123).

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary correction in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our products.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
