  11. Lock the throttle body cable adjuster (1).
  12. Important: Cables should never be adjusted so tight that tension from the cable will not allow the throttle to close completely. If the cable is adjusted to tight, the cable will prevent the engine from returning to idle and will cause unstable idle quality.

Using a scan tool check the throttle angle. When the accelerator is fully depressed the throttle angle should read 100 percent. When the accelerator is released the throttle angle should read 0 percent. If proper results are not obtained check cables for kinks or damage and repeat procedure.
