PRODUCT EMISSION CAMPAIGN AIR INJECTOR PIPE CORROSION

#### MODELS AFFECTED: 1983 BONNEVILLES AND GRAND PRIXS EQUIPPED WITH 3.8L ---------------- ENGINE (VIN CODE A) AND CALIFORNIA EMISSIONS (NB2)

#### TO: ALL PONTIAC DEALERS

General Motors has determined that some 1983 Bonneville and Grand Prix models equipped with RPO LD5 3.8L engines and California emissions may be emitting pollutants in excess of California emission standards. This may be attributed to the AIR Injection Tube corroding with increased mileage and exposure.

To correct this condition, the AIR injection tube and AIR injection check valve will be inspected and replaced, if required. In addition, the carburetor primary vacuum break is to be inspected for proper operation. When required, the primary vacuum break, if found to be inoperative, will be replaced.

Dear Pontiac Owner:

This notice is sent to inform you that Pontiac Division is initiating a recall campaign that includes your vehicle.

REASON FOR RECALL

General Motors has determined that certain 1983 Bonneville and Grand Prix models equipped with 3.8L engines and California emissions equipment may be emitting pollutants in excess of California emission standards. This may be attributed to the AIR injection tube corroding with increased mileage and exposure.

WHAT WE WILL DO

The AIR injection tube and AIR injection check valve will be inspected and when necessary, replaced. In addition, the carburetor primary vacuum break will be inspected. When required, the primary vacuum break, if found to be inoperative, will be replaced. This service will be performed for you at no charge.

WHAT YOU SHOULD DO

Contact your Pontiac dealer as soon as possible to arrange a service date. Instructions for this service have been sent to your dealer. The labor time necessary to inspect your vehicle is approximately fifteen (15) minutes. If parts are replaced, up to approximately forty (40) minutes will be required to service your vehicle. In either case, please allow some additional time for the dealer to process your vehicle.

The enclosed Owner Identification Reply Card identifies your vehicle. Presentation of this card to your dealer will assist in making the necessary inspection/correction in the shortest possible time. If you have sold or traded your vehicle bearing the identification number on this card, please let us know by completing the postage paid reply card and returning it to us so that we can correct our records. Should your dealer not schedule a service date within a reasonable time, you should contact the Pontiac Customer Assistance Center by calling 800-762-2737.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your 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.
