LACK OF POWER OR POOR ACCEL. RESTRICTED AIR INTAKE

LACK OF POWER OR LONG ACCELERATION TIME

VEHICLES AFFECTED: 1988 CAVALIER MODELS WITH ----------------- 2.0L L-4 (VIN CODE 1) AND 2.8L V-6 (VIN CODE W) EXCEPT Z24

An "as built" condition exists on the 1988 Cavalier vehicle that over time can cause customer comments of "lack of power", "doesn't accelerate", "slow", etc. An immediate under-hood inspection should be made to see if the hood blanket is restricting the fresh air intake of the air cleaner.

A section of the hood blanket should be cut out, per the figure.

Vehicles built prior to VIN JJ146831 or J7129705 may require this repair.

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.
