Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the battery to ensure safety.
  • Allow the engine to cool down if previously run.
2. Inspect and Clean the Air Intake System
  • Remove the air intake duct to access the throttle body.
  • Clean the throttle body using throttle body cleaner and a soft cloth.
  • Reinstall the air intake duct securely.
3. Fuel Pressure Check and Replacement
  • Connect a fuel pressure gauge to the fuel rail test port.
  • Turn the ignition to the "ON" position (without starting the engine) to check fuel pressure.
  • If pressure is below specifications (refer to service manual), replace the fuel pump and filter.
  • Reconnect all components and clear any trouble codes.
4. Spark Plug Inspection and Replacement
  • Remove the ignition coils and spark plugs using a socket set.
  • Inspect spark plugs for wear, fouling, or damage.
  • Replace spark plugs if necessary (use OEM recommended parts).
  • Reinstall ignition coils ensuring proper seating and connection.
5. Transmission Fluid Inspection
  • Check the transmission fluid level using the dipstick.
  • If fluid is low or discolored, drain and replace with the appropriate transmission fluid per manufacturer specifications.
  • Inspect for leaks and ensure all seals are intact.
