CAMPAIGN: NO CLOSE THROTTLE LINK CLIP INTERFERENCE
Models: 1985 Chevrolet Celebrity & Citations, Pontiac 6000, & Buick Centurys Equipped with RPO LB6 2.8L Multi-Port Fuel Injected (MFI) V-6 Engines (VIN Code W)
TO: ALL GENERAL MOTORS DEALERS
DEFECT INVOLVED:
General Motors of Canada has determined that a defect which relates to motor vehicle safety exists on some 1985 Chevrolet Celebrity and Citation, Pontiac 6000, and Buick Century models equipped with 2.-L Multi-Port Fuel Injected (MFI) V6 engines.
The throttle linkage retaining clip may interfere with the throttle body casting during normal rotation of the throttle lever. This could allow the accelerator linkage to bind and prevent the throttle from closing. If this were to occur, vehicle speed would remain constant even though the driver has removed his foot from the accelerator pedal. Loss of accelerator control could result in a vehicle crash without prior warning.

Involved are certain 1985 Chevrolet Celebrity and Citation, Pontiac 6000 & Buick Century models equipped with RPC LB6 2.8L Multi-Port Fuel Injected (MFI) V6 Engines. Vehicles involved were built within the following vehicle identification number breakpoints.

Repair Code Operation Time Allowance ----------- --------- ---------------
1A Inspect for sufficient .3 clearance between throttle linkage retaining clip and throttle body casting. If there is sufficient clearance no further action is required.
2A Inspect & if sufficient .4 clearance does not exist between throttle linkage retaining clip & throttle body casting make modifi- cation as outlined in Service Procedure.
Time allowance includes 0.1 hour for Dealer administrative detail associated with this campaign.
SERVICE
A minimal clearance condition exists on the throttle body assembly where a clip securing the throttle cable could contact a casting boss. Adequate clearance must be provided to prevent contact between the clip and boss during operation of the throttle.
1. Open Hood.
2. Refer to illustration for detailed views of the rework required.
3. Locate throttle cable clip.
4. Remove clip.
5. Slip cable off throttle cable stud.
6. To locate area of interference, install gauge bushing on throttle cable stud. Make sure gauge bushing contacts shoulder on stud while checking.
7. Slowly rotate throttle lever through full travel.
8. Bushing will contact the return spring retainer boss at area of interference. If bushing contacts boss, the boss must be filed to create clearance for the throttle cable clip.
9. Position a shop towel under boss to contain filing material.
10. The point of contact must be removed by filing to allow bushing to completely pass the boss. Leave the bushing on stud while performing filing operation.
11. Carefully file retainer boss (a 3/8 square file is recommended).
CAUTION:
USE CARE AS TO NOT DAMAGE ANY WIRING, PLASTIC VACUUM LINES, PLASTIC SPRING RETAINER, OR SPRINGS IN THE BOSS AREA.
12. Occasionally check bushing (with bushing against cable stud shoulder) to see if sufficient c learance has been achieved. When bushing clears casting through full throttle travel, stop filing. Remove the gauge bushing.
13. Remove shop towel and all filing chips.
14. Replace throttle cable on cable stud.
15. Reinstall throttle cable clip, and recheck cable operation by rotating throttle lever through full travel.
16. Close Hood.
INSTALLATION OF CAMPAIGN IDENTIFICATION LABEL
Clean surface of radiator upper mounting panel and apply a Campaign Identification Label. Make sure the correct campaign number is inserted on the label. This will indicate that the campaign has been completed.
