83ford6 Article No. 83-23-9SPEED CONTROL - SURGING
FORD 1983 MUSTANG, T-BIRD
LINCOLN-MERCURY 1983 CAPRI, COUGAR
A surging condition after vehicle speed control has been set may be caused by an inoperative circuit in the speed control servo. Because of the location of the servo on 1983 Mustang/Capri with EFI and 1983 T-Bird/Cougar, water entry may cause the servo position potentiometer to short circuit resulting in a surging condition. To service, replace the servo and install a newly released boot assembly over the servo.
For removal of the speed control servo, refer to Section 37-05-17 of the Shop Manual.
^ After removing the servo from the hinge pillar, disconnect vacuum lines and actuator cable at servo, disconnect electrical connector inside engine compartment.
^ Remove mounting bracket from old servo and install on new servo assembly.
^ Feed actuator cable hoses and wiring through hole in servo boot, part no. (E4LY-9F774-A).
^ Connect actuator cable to servo clip and fasten cable cover to servo with two nuts.
Figure 5:
^ Position boot over servo so the top side of the servo is covered and the boot opening is down. Clip boot over mounting bracket as shown in Figure 5 using fastener provided.
