Recall - Cruise Control Servo Rod Nut Installation
84olds1SUBJECT CRUISE CONTROL SERVO ROD NUT NUMBER: 84-C-2
DATE: Nov.. 14, 1983
MODELS/YEARS 1984 88's WITH 3.8L (LD5) ENGINE SECTION: 9
AND CRUISE CONTROL
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in some early production 1984 Oldsmobile 88 models equipped with 3.8L (LD5) V-6 engines and cruise control. The cruise control rod may have been assembled without a nut designed to prevent excessive travel of the throttle stud. Without this nut, the throttle stud can jam 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 throttle control could result in a vehicle crash without prior warning.
VEHICLES INVOLVED
Involved are certain early production 1984 Oldsmobile 88 models equipped with a 3.8L (LD5) V-6 engine and cruise control from the start of production through the following serial number.
Assembly Plant Serial Number
Lansing EM708611
Some vehicles within the serial number range listed have had the campaign correction performed in the assembly plant before the vehicle was shipped.
DEALER ACTION
To reduce the possibility of this occurring on vehicles involved, a nylon nut is to be added to the cruise control servo rod assembly.
Dealers are to service all vehicles subject to this campaign at no charge to the owner, regardless of mileage, age of vehicle, or ownership, from this time forward.
Whenever a vehicle subject to this campaign is taken into 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.
SERVICE PROCEDURE
1. With engine off raise the hood and remove air cleaner.

2. Locate the cruise control servo rod assembly and inspect it for the presence of a nylon nut as shown in Figure 1.
3. If a nylon nut is present install a campaign correction label as directed in Step 5.
FIGURE 1:
4. If no nut is present install a nylon nut (furnished) by snapping it into the enlarged hole in the end of the cruise control servo rod slot as shown in Figure 1.
5. Install a Campaign Correction Label. Each vehicle modified in accordance with the instructions outlined in this Service Procedure will require a Campaign Identification Label. Each label provides a space to include the campaign number, the five (5) digit dealer code of the dealer performing the campaign service, and the date vehicle was campaigned. This information may be inserted with a typewriter or ballpoint pen. When installing label, clean the surface of the radiator upper mounting support and apply the campaign label where it is readily visible.
PARTS INFORMATION
The parts required to complete this campaign (nylon nut part number 3907444) are included in the bulletin mailing to the dealers who have vehicles to correct. Additional parts may be ordered through your zone office. These parts will be provided at no charge. Due to the parts cost of one nylon nut being less than 3 cents, no parts handling allowance is to be claimed.
