CAMPAIGN: ACCELERATOR CONTROL CABLE BINDING
Models: 1987 Buick Electra/Park Avenue, Oldsmobile Delta 88/Ninety Eight, Pontiac Bonneville
TO: ALL GENERAL MOTORS DEALERS
CONDITION:
--------- General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some 1987 Electra/Park Avenue, Delta 88, Ninety Eight and Bonneville Models.
Some of these vehicles may have excessive accelerator cable friction restricting the cable's free movement between the accelerator pedal and the throttle body. This friction could be sufficient to prevent the throttle from returning to the closed (idle) position when the accelerator pedal is released. In this event, engine speed may not decrease to a level anticipated by the operator. Loss of accelerator control could result in a vehicle crash without prior warning.
DEALER ACTION
To prevent this condition, Dealers are to inspect and, if required, replace the accelerator control cable on suspected vehicles, per the Vehicles Involved and Technical Procedure sections of this bulletin.
VEHICLES INVOLVED:
Model Plant From Through ----- ----- ---- ------- Electra/Park Avenue Wentzville H1475084 H1485792
Ninety Eight Wentzville H1333413 H1334467 Orion H4342247 H4345200
Delta 88 Willow Run HW368794 HW374561 Wentzville H1838412 H1848001
Bonneville Willow Run HW291857 HW301250
All affected vehicles have been identified by the VIN listing provided to involved Dealers with this bulletin. Any Dealer not receiving a listing was not shipped any of the affected vehicles.
DEALER CAMPAIGN RESPONSIBILITY:
Dealers are to service all vehicles subject to this campaign at no charge to owners, regardless of mileage, age of vehicle, or ownership, from this time forward.
Whenever a vehicle subject to this campaign is taken into your new or used vehicle inventory, or it is in your Dealership for service in the future, you should take the steps necessary to be sure the campaign correction has been made before reselling or releasing the vehicle.
Owners of vehicles recently sold from your new vehicle inventory are to be contacted by the Dealer, and arrangements made to make the required modification according to instructions contained in this bulletin.
CAMPAIGN PROCEDURE:
Refer to Section 4 of the Service Policies and Procedures Manual for the detailed procedure on handling Product Campaigns. Dealers are requested to complete the campaign on all transfers as soon as possible.

PARTS INFORMATION:
Parts required should be ordered as "E" Items, as follows:
Part Number Description Quantity/Vehicle ----------- ----------- ---------------- 25533934 Cable, Accelerator 1 (As Required)
It is estimated that only 25% of vehicles will require an accelerator control cable. Dealers should adjust their orders accordingly.
DISPOSITION OF PARTS
Replaced parts must be held for disposition by Zone or Branch contact personnel. Parts must have a claim tag attached showing the repair order and the VIN of the vehicle from which they were removed.
PARTS AND LABOUR CLAIM INFORMATION:
Credit for the campaign work performed will be paid upon receipt of a properly completed campaign claim card, RAPID terminal or DCS transmission in accordance with the following:
Repair Code Description Time Allowance ----------- ----------- -------------- 1A Inspect for Date Code Only .3
2A Inspect and Replace Accelerator .5 Control Cable
Time allowance includes 0.1 hour for Dealer administrative detail associated with this campaign. Parts credit will be based on Dealer net plus 30% to cover parts handling.
TECHNICAL PROCEDURE:
1. Open hood, install left fender cover.
2. Inspect accelerator control cable identification band for identification (Figure 1).
- If band identification is RKS, proceed to Step 3.
- If band identification is RKT, proceed to Step 10.
3. Inspect accelerator control cable underside at the throttle body end for a four digit, white date code (Figure 1). This can be done with a small mirror, such as a dental mirror:
- If code is 7113 up to and including 7125, proceed to Step 4.
- If code is not in the 7113 up to and including 7125, proceed to Step 10.
4. Remove retainer that attaches accelerator control cable to throttle body stud (Figure 1, View A).
5. Remove accelerator control cable from engine mounted bracket by depressing accelerator control cable locking tangs (Figure 1, View B).
6. Remove lower instrument panel sound insulators and disengage accelerator control cable retainer from accelerator pedal (Figure 2). Remove retainer collar and reuse on new accelerator control cable.
7. Depress accelerator control cable locking tangs at front of dash and remove accelerator control cable (Figure 1, View B).
Install new accelerator control cable by reversing the removal procedure. Observe the following during installation of the new accelerator control cable:
Cable Installation
- Accelerator control cable must be installed in the front of dash prior to assembly to the engine.
- Accelerator control cable must not be subject to sharp bends during installation.
- Accelerator control cable must be routed smoothly and freely of wires, hoses, or other obstructions between conduit fittings.
- Accelerator control cable must be routed under TV cable.
- During installation, the braided portion of the accelerator control cable must not come in contact with front of dash sealer. This may be accomplished by pulling back on throttle end of accelerator control cable, keeping braided cable at accelerator pedal end within outer conduit while inserting in front of dash.
- Locking tangs must be expanded and locked in their attaching holes.
Cable Connection to Accelerator Pedal
- Install retainer collar from old accelerator control cable into new accelerator control cable. Refer to Figure 2.
- Slip accelerator control cable through slot in lever and then install retainer in lever, being sure it is seated. Care must be utilized in pressing the retainer into hole in lever to assure the accelerator control cable is not kinked or damaged in any way (Figure 2).
Cable Connection to Throttle Body Stud
- Retainer must be installed with tang secured over head of stud (Figure 1, View A).
8. Lube accelerator control cable pivot points with accelerator linkage lubricant.
9. Check to ensure that all components are installed correctly and that linkage and accelerator control cable is not rubbing or binding in any manner. Throttle should operate freely without binds between fully closed and wide open throttle.
10. Install a Campaign Identification Label.
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.
Dear General Motors Customer:
This notice is sent to you in accordance with the Canada Motor Vehicle Safety Act.
REASON FOR RECALL
General Motors of Canada has determined that a defect which relates to motor vehicle safety exists in some 1987 Electra/Park Avenue, Delta 88, Ninety-Eight and Bonneville Models.
Some of these vehicles may have excessive accelerator cable friction restrieting the cable's free movement between the accelerator pedal and the throttle body. This friction could be sufficient to prevent the throttle from returning to the closed (idle) position when the accelerator pedal is released. In this event, engine speed may not decrease to a level anticipated by the operator. Loss of accelerator control could result in a vehicle crash without prior warning.
WHAT WE WILL DO
To prevent the possibility of this condition occurring, the accelerator control cable will be inspected and, if required, replaced. This service will be performed for you at no charge.
WHAT YOU SHOULD DO
Please contact your GM Dealer as soon as possible to arrange a service date. Please ask your Dealer if you wish to know how much additional time will be needed to process your vehicle. The labour time to inspect your vehicle is about fifteen (15) minutes. If replacement of the accelerator control cable is required, an additional fifteen (15) minutes will be required.
And excessive high engine idle speed or failure of the vehicle to slow down as expected may be an indication of a stuck throttle. In the event a stuck throttle is suspected, the driver should apply the service brake firmly and shift the transmission to neutral.
This letter identifies your vehicle. Presentation of this letter to your Dealer will assist their Service personnel in completing the necessary correction to your vehicle in the shortest possible time.
Further assistance, if required, may be obtained from the General Motors Zone Office nearest you. Your vehicle Owner's Manual provides the location and phone number of each respective Zone Office.
We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your continued satisfaction with our products.
