2. Remove the cable housing (C) from the cable bracket (D).
3. Remove the nuts (A), then remove the accelerator pedal (B) along with the throttle cable (C) and the actuator cable (D).
4. Pull the throttle cable (C) and the actuator cable (D) out toward the passenger compartment.
5. Remove the throttle cable (A) and the actuator cable (B) from the accelerator pedal bracket (C).
6. Install in the reverse order of removal.
7. After installing, start the engine. Hold the engine speed at 3,000 rpm without load (in neutral) until the radiator fan comes on, then let it idle.
8. Hold the cable sheath, removing all slack from the cable.
9. Turn the adjusting nut (A) until it is 3 mm (1/8 in.) away from the cable bracket (B).
10. Tighten the locknut (C). The cable free play should now be 4-6 mm (3/16-1/4 in.). If free play is not within specs, loosen the locknut, turn the adjusting nut until the free play is as specified, then retighten the locknut.
