STALL, SAGS, HESITATION PROM REPLACEMENT for Pontiac 6000 1987

1987 6000 MODELS WITH LR8 2.5L ENGINE (VIN CODE R) MD9 (THM 125C) AUTOMATIC TRANSMISSION, AND F17 2.84 TRANSAXLE . Some 1987 6000 models equipped with 2.5L LR8 engines, automatic transmissions, and 2.84 transaxle may exhibit driveability conditions such as idle shake, sag on a light throttle application from a standing start, when engine is at operating temperature, and a stall on the same light throttle application if done immediately after a cold start at ambient temperatures 80 to 85 degrees Fahrenheit.

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.
