why does my Honda Accord have poor fuel economy after service

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Disconnect the negative terminal of the battery to ensure safety during inspection.

2. Inspect Air Filter

• Remove the air filter housing cover using a socket set.
• Take out the air filter and inspect it for dirt and debris.
• If the air filter is dirty, replace it with a new one, ensuring it fits properly before reassembling the housing.

3. Check Tire Pressure

• Use a tire pressure gauge to measure the pressure of all four tires.
• Inflate tires to the specified pressure listed on the driver’s door jamb.
• Replace any damaged tires if necessary.

4. Inspect Fuel System

• Disconnect the fuel pump relay and relieve fuel system pressure by starting the engine until it stalls.
• Replace the fuel filter if it has not been done or if it appears clogged.
• Use a fuel pressure gauge to check pressure at the fuel rail; compare with manufacturer specifications.

5. Examine Exhaust System

• Inspect the exhaust system visually for any blockages or holes, particularly around the catalytic converter.
• If blockage is found, consult the service manual for removal and replacement procedures.
