CONDITION
General Motors has determined that some 1983 Oldsmobile Cutlass Supreme, Cutlass Supreme Brougham, Cutlass Calais, Cutlass Cruiser, and Delta 88
models equipped with RPO LD5 3.8L engine and California emissions may be emitting pollutants in excess of California emission standards. This may
be attributed to the air injection pipe corroding with increased mileage and exposure.

engine (VIN Code A) and California emissions (NB2).
