Solution

1. Tire Maintenance

Check tire pressure: Use a tire pressure gauge to measure each tire's pressure. Inflate tires to the recommended PSI found on the driver’s door jamb.
Rotate tires: If uneven wear is observed, rotate tires every 5,000 to 7,500 miles.
Alignment: If tire wear is excessive, perform a wheel alignment.

2. Air Filter Replacement

Locate the air filter: Open the hood and find the air intake box.
Remove the old filter: Unclip or unbolt the air intake box, carefully remove the air filter, and inspect it for dirt or damage.
Install a new filter: Place a new, clean air filter in the intake box, ensuring a snug fit, and reattach the cover.

3. Fuel System Cleaning

Add fuel system cleaner: Purchase a high-quality fuel system cleaner and follow the instructions for dosage relative to your fuel tank capacity.
Consider professional cleaning: If performance doesn’t improve, consider having a professional perform a fuel injector cleaning service.

4. Driving Habits Modification

Practice smooth driving: Encourage gradual acceleration and braking, reducing sudden starts and stops.
Avoid excessive idling: Turn off the engine during long stops to save fuel.
Use cruise control: When on the highway, utilize cruise control to maintain a steady speed.

5. Regular Maintenance

Oil change: Use the manufacturer-recommended oil type and change it regularly according to the service schedule.
Check spark plugs: Inspect and replace spark plugs if they show signs of wear or if the vehicle has high mileage (recommended interval is typically 100,000 miles).
