REVISED DIAGNOSTIC CHARTS '86 PRELIMINARY SHOP MANUALS

MODELS/YEARS: 1986 CUTLASS CIERA, CUTLASS SUPREME AND CUSTOM CRUISER

Certain Driveability and Emissions - Carbureted Diagnostic Charts have been revised for 1986 models.

Please update the applicable pages of your 1986 Oldsmobile New Product Service Information Manual - All Series Except Toronado with this revised information.

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.
