Solution

1. Tire Maintenance

Checking Tire Pressure: Use a tire pressure gauge to check each tire's pressure. Inflate tires to the recommended PSI listed on the driver’s door jamb.
Tire Rotation: Rotate tires every 5,000 to 7,000 miles to ensure even wear, which can improve fuel efficiency.

2. Air Filter Replacement

Remove Air Filter Housing: Use a socket set to remove the screws or clips securing the air filter housing.
Replace Air Filter: Take out the old air filter and replace it with a new one. Ensure it fits snugly and securely in the housing.

3. Fuel System Cleaning

Add Fuel Injector Cleaner: Purchase a quality fuel injector cleaner and pour it into the fuel tank as per the instructions on the product.
Consider Professional Cleaning: If performance does not improve, consider having a professional clean the fuel injectors.

4. Regular Maintenance Checks

Oil Change: Change the engine oil and filter every 5,000 to 7,500 miles. Use the viscosity recommended in the owner’s manual.
Spark Plug Replacement: Inspect and replace spark plugs if they are worn or dirty to ensure optimal ignition.

5. Driving Habits Improvement

Smooth Acceleration: Avoid rapid starts and stops. Accelerate gradually and anticipate stops to reduce fuel consumption.
Limit Idling: Turn off the engine if stationary for more than a minute to save fuel.
