Ensure the throttle cable bracket is not bent or loose before making this adjustment, and confirm that the rubber boot is properly seated on the adjuster. Press the accelerator pedal fully to the floor, ensuring the throttle cable in the throttle body is completely open; check and adjust if necessary. Measure the distance the stopper or painted mark on the cable extends from the boot, aiming for a clearance of 1.0 mm between the end of the rubber boot and the stopper, adjusting as needed to achieve the proper length. If the boot-to-stopper clearance is not as specified, loosen and back off the outer adjusting nut, then turn the inner adjusting nut to move the cable housing as required to achieve the specified clearance, ensuring to tighten the outer nut to lock the housing in position.
