Cutlass V8-307 5.0L VIN 9 4-bbl HP (1984)
Technical Service Bulletin # 88C079B
Date: 890701
Recall - Servo Bail Bushing
Subject:
Servo Bail Bushing
Models/Years:
Certain 1984-88 Oldsmobile
Vehicles With Cruise Control (RPO K34) on Certain Gasoline. & Diesel Engines
Number:
88-C-07
Date:
July 1989
Section:
9B
CONDITION
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1984 through 1988 Oldsmobile model vehicles
equipped with cruise control (RPO K34) on certain gasoline & diesel engines. A small nylon bushing in the cruise control servo bail (bracket) may slip
out of place. This will not affect the operation of the cruise control, but it may cause intermittent increases in engine speed or dieseling (engine run-on
with ignition off). If the vehicle is not serviced and the nylon bushing remains out of place, the servo, rod assembly could wear through the bail. If the
rod wears through the bail, it may catch on other engine components and possibly result in a stuck throttle. Although the vehicle can still be stopped with
the service brake, an unexpected loss of accelerator control could result in a vehicle crash.

Vehicles with Part Number 25074629 or Part Number 12335036 replacement Cruise Control Servos do not require the Bushing Kit called for in this
Product Campaign Bulletin. Oldsmobile has eliminated a number of vehicles from this campaign which it was able to identify from warranty records as
having the above replacement Servos installed. However, a large number of vehicles may have had the P/N 25074629 and P/N 12335036 Servos
installed beyond warranty; those vehicles must be identified by inspection.
DEALER ACTION
To prevent this condition from occurring, dealers are to install a Bushing Kit on the Cruise Control Servo Bail. The cruise control servo assembly is not
authorized as a replacement to correct for a missing or out of place bushing. Also, if other repairs are needed to the cruise control system, and the vehicle
is out of warranty, the repair would be at the owner's expense.
Dealers are to perform this campaign on all involved vehicles 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 now or used car inventory, or it is in your dealership for service, you are to ensure the
campaign correction has been made before selling or releasing the vehicle.
