HIGH IDLE SPEED/POSSIBLE CEL CHECK EGR PIPE FOR LEAK

VEHICLES AFFECTED: 1985-87 FIERO WITH 2.8L V6 (VIN CODE 9) ENGINES

Some 1985-87 Fieros with 2.BL V6 (VIN Code 9) engines may experience a high engine idle speed, possibly with a check engine light and a stored trouble code 35.

In addition to the causes described for this condition in section 6E3 of the Service Manual is the possiblity of an induction leak due to a crack in the EGR pipe adjacent to the flange at the intake plenum (see Figure 1). Inspect this area by gently pulling aside the insulator sleeve.

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.
