# HIGH IDLE SPEED/POSSIBLE CEL CHECK EGR PIPE FOR LEAK

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

Some 1985-87 Fiero models with 2.8L 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 possibility 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.
