  1. Check the throttle body for cracks.
  2. Check for restriction in the vacuum port or passage
  3. Check for interference when moving the accelerator cable.
    CAUTION:
    • Throttle valve set screw was adjusted in the production line with the air volume (0.516 +/- 5% g/sec) during idling. So please DO NOT ADJUST IT voluntarily.
    • When the idle RPM is out of specification, check the relevant sensors and their input or output value first.
    • The throttle body does not need to be cleaned because carbon in throttle body does not affect the system's operation at all.
