Solution
1. Preparation
  • Tools Required: OBD-II scanner, socket set, torque wrench, multimeter, vacuum gauge.
  • Ensure the vehicle is parked on a flat surface and the engine is cool. Disconnect the battery before starting work.
2. Code Diagnosis
  • Using the OBD-II scanner, retrieve and note down any trouble codes. Research the codes to determine potential issues.
  • Clear the codes and take the vehicle for a test drive to see if the codes reappear.
3. Visual Inspection
  • Inspect the gas cap: Ensure it is tight and free from damage. Replace if necessary.
  • Check for leaks: Look for any visible leaks in hoses and around the engine. Repair or replace any damaged hoses.
4. Ignition System Check
  • Remove spark plugs using a socket set. Inspect for wear and carbon buildup.
  • Test ignition coils with a multimeter for proper resistance. Replace any faulty components.
5. Fuel System Examination
  • Connect a fuel pressure gauge to the fuel rail. Start the engine and check for the proper fuel pressure as specified in the service manual.
  • If the pressure is low, inspect the fuel pump and filter for clogs or failure.
6. Final Steps
  • Reconnect the battery and clear any codes again. Conduct a final test drive to verify the issue has been resolved.
