TECHNICAL PROCEDUREA minimal clearance condition exists on the throttle body assembly where a clip securing the throttle cable might contact a casting boss. Added clearance must be provided to prevent contact of the clip and boss during operation of the throttle.
1. Open hood.
CAMPAIGN 85-C-2 INSPECTION AND MODIFICATION PROCEDURE:
2. Refer to illustration for detailed views of the work required.
3. Locate throttle cable clip.
4. Remove clip. Do not lose or damage clip; it will be reused.
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).
NOTICE: 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 clearance 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. Install campaign label upon completion of the inspection and/or modification.
Each vehicle modified in accordance with the instructions outlined in this Product Campaign Bulletin will require a "Campaign Identification Label". Each label provides a space to include the five-digit dealer code of the dealer performing the campaign service. This information may be inserted with a typewriter or ballpoint pen.
Each "Campaign Identification Label" is to be located on the radiator core support in an area which will be visible when the vehicle is brought in for periodic servicing by the owner.
Apply "Campaign Identification Label" only on a clean dry surface.

Dear Buick Owner:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
General Motors has determined that a defect which relates to motor vehicle safety exists on some 1985 Skylarks equipped with 2.8L Multi-Port Fuel Injected V6 Engines. The throttle linkage retaining clip might interfere with the throttle body casting during normal rotation of the throttle lever. This could prevent the throttle from closing 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.
To prevent this from occurring on your vehicle, please contact your Buick Dealer to arrange a service date. The dealer will add clearance between the accelerator linkage and throttle body casting. This service will be completed for you at no charge.
Instructions have been sent to your Buick Dealer. The labor time to do the work will be about 20 minutes. Please ask your dealer if you wish to know how much additional time will be necessary to process your vehicle.
Your Buick Dealer is best equipped to provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date or within five (5) days, we recommend you contact the Customer Assistance Department, Flint home office, by calling:
800-521-7300, for all except residents of Alaska and Hawaii. In Alaska, call (503) 641-8350. In Hawaii, call (805) 497-8561.
