REVISED ELECTRONIC FUEL INJECTION DIAGNOSTIC CHARTS

Included with this bulletin are four diagnostic charts; two are new charts and two have been revised.

Due to printing schedules, these charts were not included in the 1983 Pontiac Service Manual. Please insert these revised charts in Section 6E2 when your new Service Manual arrives.

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.
