Solution

1. Tire Maintenance

Inflate Tires: Use a tire pressure gauge to check the tire pressure. Inflate tires to the manufacturer's recommended PSI.
Rotate Tires: If uneven wear is present, rotate tires according to the manufacturer’s schedule to ensure even tread wear.

2. Air Filter Replacement

Locate the Air Filter: Open the hood and find the air intake box.
Remove the Old Filter: Unscrew or unclamp the housing to access the air filter. Remove the filter and inspect for dirt and debris.
Install New Filter: Insert the new air filter, ensuring it is seated correctly. Reattach the housing securely.

3. Engine Tune-up

Inspect Spark Plugs: Remove spark plugs using a socket set. Check for wear or carbon buildup.
Replace if Necessary: Replace worn spark plugs with new ones according to the manufacturer’s specifications (typically NGK or Denso for Honda).
Clear Codes: If any engine codes were found during diagnostics, clear them using the OBD-II scanner after repairs.

4. Fuel System Clean

Add Fuel Injector Cleaner: Pour a quality fuel injector cleaner additive into the fuel tank as per the product instructions.
Use High-Quality Fuel: Always use fuel from reputable stations that meet or exceed octane recommendations.

5. Driving Habits Adjustment

Adopt Smooth Driving Techniques: Encourage gradual acceleration and deceleration. Avoid excessive idling and maintain a steady speed.
Limit Use of Air Conditioning: Use air conditioning sparingly, as it can reduce fuel efficiency.
