In addition, check spark plugs for fuel fouling and replace if necessary. Use care when removing spark plug wire boots from spark plugs. Twist the boot one-half turn before removing, and pull on the boot only to remove the wire. Check to make sure plug wires are routed correctly and through the proper retainers.

Use applicable labor operations.

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.
