why is my Honda Civic using too much gas

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is cool.
• Disconnect the battery to prevent electrical shocks.

2. Replace Air Filter

• Locate the air filter housing, typically near the engine bay.
• Remove the clips or screws securing the housing.
• Take out the old air filter and clean the housing with a damp cloth.
• Insert the new air filter and secure the housing back in place.

3. Clean or Replace Fuel Injectors

• Remove the fuel injector rail from the engine by unscrewing the bolts.
• Disconnect the electrical connectors and fuel lines carefully.
• Use a fuel injector cleaning kit or ultrasonic cleaner to clean the injectors.
• Reinstall the cleaned or new injectors back into the rail and secure.

4. Test and Replace Oxygen Sensors (if necessary)

• Locate the oxygen sensors in the exhaust system.
• Disconnect the wiring harness from the sensors.
• Use a wrench to unscrew and remove the sensors.
• Install new sensors by screwing them in and reconnecting the wiring.

5. Check and Adjust Tire Pressure

• Use a tire pressure gauge to measure the pressure of each tire.
• Inflate or deflate tires to match the recommended PSI (found on the driver's door jamb).
• Inspect tires for uneven wear and replace if necessary.
