Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
2. Retrieve Error Codes
  • Use the OBD-II scanner to retrieve the error codes and note them for reference.
  • Clear the error codes and monitor if they reappear after a test drive.
3. Inspect and Replace Components
  • Gas Cap Inspection
    • Check for cracks or wear; replace if necessary.
  • Spark Plug Replacement
    • Remove ignition coils and spark plugs using a socket wrench.
    • Inspect plugs for wear; replace with new OEM spark plugs.
    • Torque spark plugs to manufacturer's specifications (usually around 13-16 lb-ft).
  • Air Filter Replacement
    • Open the air filter housing and replace the air filter if it is clogged.
4. Sensor Inspection and Replacement
  • Mass Airflow Sensor
    • Disconnect the MAF sensor and inspect for dirt; clean with MAF cleaner if necessary.
    • Replace if damaged.
  • Oxygen Sensor
    • Locate the upstream and downstream oxygen sensors, disconnect, and replace if faulty.
    • Torque new sensors to the manufacturer's specifications (typically around 30 lb-ft).
