Solution
1. Preparation
  • Gather necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety while working on electrical components.
2. Replace Air Filter
  • 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 (ensure it matches OEM specifications).
  • Reattach the air filter housing cover and tighten to manufacturer specifications.
3. Inspect and Replace Spark Plugs
  • Remove the ignition coil assembly (if applicable) using a socket set.
  • Unscrew the spark plugs using a spark plug socket.
  • Inspect spark plugs for wear, and if necessary, replace them with new ones (use OEM recommended plugs).
  • Torque new spark plugs to the manufacturer’s specified value (usually around 13 lb-ft for Honda).
  • Reinstall ignition coils securely.
4. Clean Fuel Injectors
  • Remove fuel injector rail (ensure fuel pressure is relieved before this step).
  • Use a fuel injector cleaner or ultrasonic cleaner to clean the injectors.
  • Reinstall the fuel injectors with new O-rings if necessary.
  • Reattach the fuel rail and ensure all connections are secure.
5. Test Throttle Position Sensor (TPS)
  • Disconnect the TPS connector.
  • Using a multimeter, check the resistance across the TPS terminals and compare with specifications.
  • If the TPS is out of range, replace it with a new one, ensuring proper alignment and connection.
