Idle Speed: Sidekick

  1. Start engine, and warm it to operating temperature. Turn all accessories off. Ensure all fuel and emission control system wire connectors and hoses are properly connected. Ensure accelerator cable has free play at throttle body. Ensure ignition timing is correct. See IGNITION TIMING  table under IGNITION TIMING. Ensure air cleaner and ducts are properly installed and air filter element is in good condition.
  2. Connect service wire between terminals "B" (diagnosis switch) and "C" (ground) of monitor coupler. See Figure . Ensure MIL (CHECK ENGINE light) indicates Code 12. Turn engine off, and connect Duty Meter (99963-00006) to monitor coupler duty terminals "A" (output) and "C" (ground). Test connector is located near battery. Connect tachometer.
  3. Start engine, and warm it to operating temperature. Ensure idle speed and IAC duty percentage are within specification. Refer to the appropriate IDLE SPEED SPECIFICATIONS  table in this article and/or the IAC DUTY AT SPECIFIED IDLE SPEED  table. If idle speed and/or IAC duty percentage require adjustment, remove idle speed adjusting screw protective cap on throttle body. Turn idle speed adjusting screw to adjust idle to specification. See Figure .

If vehicle is not equipped with A/C, reinstall idle speed adjusting screw protective cap to throttle body and remove service jumper wire. Remove duty meter from monitor coupler, and reinstall cap.
  5. Turn A/C on, and set fan switch to LOW position. Check idle speed and IAC duty percentage with A/C on. If idle speed and IAC duty percentage are not as specified, turn A/C VSV adjusting screw to adjust idle to specification. See Figure .
