Recall - EGR Vacuum Signal Relocation: Overview
Model Year 1982Bulletin No. 82-C-16
File in Group 64
Number 45
Date May '86
SUBJECT: PRODUCT EMISSION CAMPAIGN NOx EMISSIONS
MODELS AFFECTED: 1982 SKYHAWKS EQUIPPED WITH 1.8L ENGINE (VIN CODE G) AND CALIFORNIA EMISSIONS
General Motors has determined that some 1982 Buick Skyhawk models equipped with RPO L46 1.8L engine (VIN Code G) and California emissions may be emitting NOx pollutants in excess of California Emission Standards. This may be attributed to the E.G.R. valve vacuum signal becoming inadequate with increased mileage.
To correct this condition, the source of the EGR vacuum signal is being relocated to provide increased vacuum, thereby reducing the NOx emission level. In addition, the carburetor secondary vacuum break is to be inspected for proper operation.
VEHICLES INVOLVED
All 1982 Buick Skyhawk models equipped with RPO L46 1.8L engine (VIN Code G) and California emissions.
