why is my Honda Accord using more fuel than before

Solution

1. Preparation

• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the engine is off and cool.
• Disconnect the battery before working on electrical systems.

2. Replace Air Filter

• Remove the air filter housing cover using a screwdriver.
• Take out the old air filter and inspect the housing for debris.
• Insert a new, clean air filter (ensure it matches OEM specifications).
• Reattach the housing cover securely.

3. Test and Replace Fuel Injectors (if necessary)

• Remove the fuel injector rail by loosening the bolts with a socket set.
• Disconnect the electrical connectors from the fuel injectors.
• Use a multimeter to test injectors for resistance; replace any that are out of spec.
• Clean or replace clogged injectors as needed, ensuring proper seating when reassembling.

4. Check and Replace Oxygen Sensors (if faulty)

• Locate the oxygen sensors (upstream and/or downstream) based on service manual.
• Disconnect the electrical connectors and remove the sensors using an oxygen sensor socket.
• Install new oxygen sensors and reconnect electrical connectors.

5. Inspect and Adjust Tire Pressure

• Use a tire pressure gauge to check the pressure in all tires.
• Inflate tires to the recommended pressure specified in the owner’s manual.
• Inspect for uneven wear or alignment issues, correcting as necessary.
