Solution
1. Preparation
  • Gather the necessary tools and parts.
  • Disconnect the battery to ensure safety while working on the electrical systems.
  • Allow the engine to cool if recently operated.
2. Address Engine Codes
  • If any codes were found in the diagnostic step, clear them using the OBD-II scanner.
  • If the issue persists, note the specific codes for further investigation.
3. Inspect and Clean Air Intake
  • Remove the air intake duct and inspect for cracks or loose connections.
  • Clean the air filter and replace if necessary. Ensure it is seated properly.
  • Clean the throttle body using throttle body cleaner and a soft cloth, ensuring no debris enters the intake manifold.
4. Fuel System Inspection
  • Connect the fuel pressure gauge to the fuel rail and turn the ignition on (do not start the engine) to check the fuel pressure.
  • If the pressure is low, inspect the fuel pump and replace if necessary.
  • Replace the fuel filter if it hasn’t been replaced according to the maintenance schedule.
5. Ignition System Maintenance
  • Remove and inspect the spark plugs for wear or fouling; replace with OEM parts if needed.
  • Test the ignition coils for proper functionality using a multimeter; replace any defective coils.
6. Exhaust System Check
  • Inspect the exhaust system, focusing on the catalytic converter for signs of blockage or damage.
  • If a blockage is found, replace the affected component to restore proper exhaust flow.
