'I . Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in $ or@ oosition, M/T in neutral) until
the radiator fan comes on, then let it idle.
2. Check that the throttle cable operates smoothly with
no binding or sticking. Repair as necessary.
3. Check cable free play at the throttle linkage. Cable
deflection should be 1O-12 mm (O.39-O.47 in.)

4.lf deflection is not within specs, loosen the locknut
and turn the adjusting nut until the deflection is as
specifled.
With the cable properly adjusted. check the throttle
valve to be sure it opens fully when you push the
accelerator pedal to the floor. Also check the throt-
tle valve to be sure it returns to the idle oosition
whenever you release the accelerator pedal.
Installation
1. Fully open the throttle valve. then install the throt-tle cable in the throttle linkage and install the cablehousing in the cable bracket.
2. Start the engine. Hold the engine at 3,OOO rpm withno load (A/T in S or @ position, M/T in neutrall untilthe radiator tan comes on, then let it idle.

THROTTLE LI K
With part A of the cabl€ bracket, support the cable
sheath so that there is no inner wire free play. Turn
the adjusting nut until it touches part A, leaving a
gap between the locknut and adiusting nul.
Move the cable sheath to psrt B of the cable brack-
et that so the bracket slides into the gap between
the locknut and adiusting nut. Tighten the locknul.
