Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a level surface and the engine is cool.
  • Disconnect the battery before performing any electrical work.
2. Air Filter Replacement
  • Remove the air filter housing cover using a socket set.
  • Take out the old air filter and inspect the housing for debris.
  • Install a new air filter, ensuring it is seated properly.
  • Reattach the air filter housing cover and secure it.
3. Fuel Injector Cleaning/Replacement
  • Disconnect the fuel lines from the injectors with appropriate wrenches, taking care to relieve fuel pressure first.
  • Remove the fuel injectors from the fuel rail.
  • Clean the injectors using a professional-grade cleaning kit or replace them if they are clogged.
  • Reinstall the injectors into the fuel rail and reconnect the fuel lines securely.
4. Spark Plug Inspection/Replacement
  • Remove the ignition coil covers and disconnect the coils.
  • Use a spark plug socket to remove each spark plug.
  • Inspect the spark plugs for wear; replace them if they are fouled or worn.
  • Install new spark plugs with the proper torque specification (typically around 13-15 lb-ft).
5. Exhaust System Inspection
  • Visually inspect the exhaust system for any visible damage or blockages.
  • Check for any leaks at joints or around the catalytic converter.
  • Replace any damaged components or clear blockages as needed.
