Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety.
  • Allow the engine to cool before starting repair.
2. Inspect and Clean Throttle Body
  • Remove the air intake duct connected to the throttle body using a socket set.
  • Use throttle body cleaner and a soft cloth to clean the interior of the throttle body.
  • Ensure the throttle plate moves freely and does not stick.
  • Reinstall the air intake duct securely.
3. Replace Fuel Filter (if applicable)
  • Locate the fuel filter on the vehicle.
  • Use a wrench to disconnect the fuel lines from the filter, taking care to catch any spilled fuel.
  • Remove the old fuel filter and replace it with a new one.
  • Reconnect the fuel lines and ensure they are secure.
4. Clean or Replace Mass Airflow Sensor (MAF)
  • Disconnect the electrical connector from the MAF sensor.
  • Remove the MAF sensor from its housing using a screwdriver.
  • Clean the MAF sensor with MAF cleaner. If damaged, replace with a new sensor.
  • Reinstall the MAF sensor and reconnect the electrical connector.
5. Inspect and Replace Spark Plugs (if worn)
