Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is parked on a flat surface and the engine is cool.
  • Disconnect the battery to prevent electrical shorts.
2. Clean the Throttle Body
  • Remove the air intake duct connected to the throttle body.
  • Use throttle body cleaner and a soft cloth to clean the throttle plate and surrounding areas.
  • Reattach the air intake duct securely.
3. Replace Spark Plugs and Ignition Coils
  • Remove the engine cover if applicable.
  • Disconnect the ignition coil connectors and remove the bolts securing the coils.
  • Pull out the old spark plugs using a spark plug socket and ratchet.
  • Install new spark plugs to the manufacturer's torque specifications (usually around 13-15 ft-lbs).
  • Reinstall the ignition coils and reconnect the connectors.
4. Inspect and Replace Vacuum Hoses
  • Visually inspect all vacuum hoses for wear and tear.
  • Replace any damaged hoses with OEM or equivalent parts.
  • Ensure all connections are tight.
5. Test and Replace Idle Air Control Valve (if necessary)
  • Disconnect the IAC valve connector.
  • Remove the IAC valve from its mounting.
  • Test the valve with a multimeter to check its resistance (consult vehicle service manual for specific values).
  • Replace the IAC valve if it is out of specification.
