PRODUCT SAFETY CAMPAIGN 88-C-21 SERVO BAIL BUSHING
MODELS AFFECTED
Certain 1984-88 Pontiac Vehicles
With Cruise Control (RPO K34) on Certain Gasoline & Diesel Engines
To:Zone Managers
DEFECT INVOLVED
General Motors has determined that a defect which relates to motor vehicle safety exists in some 1984 through 1988 Pontiac model vehicles equipped
with cruise control 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.

Involved are certain 1984 through 1988 Pontiac vehicles equipped with Cruise Control (RPO K34) and 5.OL or 5.7L engines within the following VIN

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.
