Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the battery to ensure safety during repairs.
2. Replace Fuel Filter
  • Locate the fuel filter, which is usually along the fuel line.
  • Sub-steps:
    • Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
    • Disconnect the fuel lines from the filter using appropriate wrenches.
    • Remove the filter from its bracket.
    • Install the new filter, ensuring the flow direction matches the markings on the filter.
    • Reconnect the fuel lines securely.
3. Clean or Replace Fuel Injectors
  • Remove the fuel injectors from the fuel rail.
  • Sub-steps:
    • Utilize a fuel injector cleaning kit or ultrasonic cleaner to clean the injectors.
    • If injectors are severely clogged or damaged, replace them with new units.
    • Reinstall the cleaned or new injectors into the fuel rail.
4. Inspect and Repair Air Intake System
  • Visually inspect the air intake components for cracks or loose connections.
  • Sub-steps:
    • Tighten any loose clamps and replace any damaged hoses.
    • Clean the throttle body using an appropriate throttle body cleaner.
5. Verify Fuel Pressure
  • Reconnect the fuel pressure gauge to the fuel rail.
  • Sub-steps:
    • Turn the ignition to the "On" position (without starting the engine) to check the pressure reading.
    • Ensure that the pressure reading falls within the specifications provided in the service manual.
