Solution
1. Preparation
  • Gather tools and parts required for repairs.
  • Disconnect the negative battery terminal to ensure safety.
  • Allow the engine to cool down.
2. Replace Air Filter
  • Remove the air filter housing cover using a screwdriver or socket set.
  • Take out the old air filter and inspect for dirt or damage.
  • Insert a new air filter, ensuring it fits snugly.
  • Reattach the air filter housing cover securely.
3. Clean Throttle Body
  • Locate the throttle body and remove the intake duct.
  • Use throttle body cleaner and a soft cloth to clean the inside of the throttle body.
  • Ensure no debris enters the intake manifold.
  • Reattach the intake duct and tighten all clamps and screws.
4. Replace Spark Plugs
  • Locate the spark plug wires and remove them carefully.
  • Use a socket wrench to unscrew the old spark plugs.
  • Install new spark plugs, ensuring to use the correct gap specifications (typically 0.044 inches for most Honda models).
  • Reconnect spark plug wires to their respective plugs.
5. Test Fuel Pressure
  • Connect a fuel pressure gauge to the fuel rail's test port.
  • Turn the ignition to the "ON" position (do not start the engine) and check the pressure reading against manufacturer specifications (usually around 30-50 psi).
  • If pressure is low, check the fuel pump relay and wiring; replace the fuel pump if necessary.
