ACCELERATOR LINKAGE - DIAGNOSTIC PROCEDURE
LIGHT TRUCKS 1980-83 LIGHT TRUCKS
Servicing of Cable-Type Acceleration Linkage
The following procedure will assist in diagnosing accelerator linkage concerns on 1980-83 light trucks.
If the accelerator pedal, when operated, is hard to push down or feels "raspy" or "sticky", perform the following:
1.
First disconnect the accelerator cable from the carburetor (or injector pump) throttle lever ball stud. Also disconnect the cruise control from the
accelerator cable if so equipped.
2.
Then check the following items:
^
Be sure that the disconnected end of the cable or its spring does not come into contact with any of the surrounding parts.
^
Operate the pedal by foot.
^
If accelerator operation is smooth, the pedal assembly and cable are not the cause of the concern. Refer to the carburetor/injector pump
diagnosis procedures in the appropriate shop manual for additional checks.

^
F Series with the 6.9L Diesel Engine - See the 1983 Car/Truck Shop Manual - Engine Electronics Section 25-64.
^
If the concern persists (being sure disconnected end of cable has not come into contact with anything), check foot pedal assembly for free
operation. If pedal operation is free, replace the cable.
If you have a high engine idle speed concern, check the following linkage systems:
1.
First disconnect the accelerator cable from the carburetor (or injector pump) throttle lever ball stud. Also disconnect the cruise control from the
accelerator cable if so equipped.
^
If the cable ball socket extends beyond the throttle lever ball stud, refer to the carburetor
diagnosis procedures in the appropriate shop manual for the correct adjustment procedure.
^
If the socket does not extend beyond the stud, check the foot pedal assembly for free operation. If the pedal operation is free, replace the cable.
NOTE:
The accelerator cable should not be lubricated and it is not serviceable.
