Solution
1. Preparation
  • Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, and diagnostic manual.
  • Ensure the vehicle is parked on a level surface and the engine is cool.
  • Disconnect the battery to prevent electrical shorts.
2. Address Error Codes
  • Connect the OBD-II scanner to the diagnostic port.
  • Record the error codes and refer to the service manual for detailed descriptions.
  • Clear the codes and take the vehicle for a test drive to see if they reappear.
3. Inspect and Replace Components

A. Air Filter

  • Remove the air filter cover using a socket set.
  • Inspect the air filter; if dirty, replace it with a new one.
  • Reinstall the air filter cover securely.

B. Spark Plugs

  • Remove ignition coil bolts with a socket set and disconnect the wiring harness.
  • Remove spark plugs using a spark plug socket; inspect for wear or damage.
  • Replace with new spark plugs as per manufacturer specifications (usually torque to 13 lb-ft).
4. Check Fuel System
  • Inspect fuel lines and connections for any visible leaks.
  • Test fuel pressure using a fuel pressure gauge; replace the fuel pump if pressure is below specifications.
5. Final Assembly
  • Reconnect any components removed during inspection.
  • Reconnect the battery and ensure all electrical connections are secure.
  • Start the engine to check for any warning lights.
