Solution
1. Preparation
  • Gather tools: OBD-II scanner, fuel pressure gauge, socket set, multimeter, air filter cleaner, cleaning cloths.
  • Ensure the vehicle is parked on a level surface and the engine is cool before starting work.
2. Address Error Codes
  • Use the OBD-II scanner to read any diagnostic trouble codes (DTCs).
  • Clear the codes and take the vehicle for a test drive to see if they return.
  • If codes reappear, repair the underlying issues indicated by the codes.
3. Clean or Replace Air Filter
  • Remove the air filter housing cover using a socket set.
  • Inspect the air filter for dirt and debris.
  • If dirty, clean it with compressed air or replace it with a new filter.
  • Reassemble the air filter housing.
4. Fuel System Check
  • Connect the fuel pressure gauge to the fuel rail's Schrader valve.
  • Start the engine and monitor the fuel pressure; it should meet the manufacturer's specifications (typically 30-45 psi for Honda Civic).
  • If pressure is low, check the fuel pump and filter for blockages or failures.
5. Inspect and Replace Spark Plugs
  • Remove the ignition coil or spark plug wires depending on the configuration.
  • Use a socket to remove the spark plugs and inspect their condition.
  • Replace any worn or fouled spark plugs with OEM equivalents, ensuring proper gap specifications.
  • Reinstall the ignition coils or spark plug wires.
6. Throttle Body Cleaning
  • Remove the intake duct connected to the throttle body.
  • Use throttle body cleaner and a cleaning cloth to remove carbon buildup from the throttle plate and housing.
  • Reassemble the intake duct and ensure all connections are secure.
