Subject: 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.
