1. Turn A/C and lights OFF. Inspect and adjust at no
load.
2. Warm engine until stabilized at idle.
3. Confirm idle speed is at standard value.
Standard value:
750 ± 50 r/min <4G1>
750 ± 100 r/min <4G6>
4. Stop engine. [ignition switch: LOCK (OFF)
position].
5. Confirm there are no sharp bends in the
accelerator cable.
6. Check the inner cable for correct slack.
Standard value: 1.0 − 2.0 mm
7. If there is too much slack or no slack, adjust play
by the following procedures.
(1) Loosen the adjusting bolts to release the
cable.
(2) Move the plate until the inner cable play is at
the standard value, and then tighten the
adjusting bolts.
(3) After adjusting, check that the throttle lever is
touching the stopper. Item Standard value
