# CLARIFICATION OF EMISSIONS LABEL INFORMATION

THE BROUGHAM SERVICE INFORMATION MANUAL SECTION 6E1-C2 OUTLINES THE PROCEDURE FOR ADJUSTING THE IDLE LOAD COMPENSATOR. STEP 1 OF THIS PROCEDURE REFERS TO THE "VEHICLE EMISSIONS CONTROL LABEL", SEE FIGURE 1. THIS LABEL OUTLINES VARIOUS SPECIFICATIONS SUCH AS TIMING, SPARK PLUG GAP, AND FAST IDLE SPEED. THE SPECIFIED IDLE SPEED OF 550 RPM IS THE FAST IDLE SPEED ON THE LOW STEP OF THE FAST IDLE CAM. THIS SHOULD NOT BE CONFUSED WITH THE CURB IDLE SPEED OF 450 RPM PLUS/MINUS 25 RPM. CURB IDLE SPEED IS LISTED IN STEP 11 OF THE "IDLE LOAD COMPENSATOR ADJUSTMENT" PROCEDURE, PAGE 6E1-C2-10.

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.
