Solution

1. Preparation

Gather tools and materials: OBD-II scanner, tire pressure gauge, new air filter, cleaning supplies.
Ensure vehicle is parked on a level surface and the engine is off.

2. Tire Maintenance

Check Tire Pressure
- Use a tire pressure gauge to measure air pressure.
- Inflate tires to the recommended PSI found on the door jamb or owner's manual.
Tire Rotation
- Lift the vehicle using a jack and secure with jack stands.
- Remove lug nuts using a socket set and rotate tires according to the manufacturer's recommendation.

3. Air Filter Replacement

Remove Old Air Filter
- Locate the air filter housing (usually near the engine).
- Unclip or unscrew the housing cover.
- Remove the old air filter.
Install New Air Filter
- Clean inside the housing with a cloth.
- Insert the new air filter, ensuring it fits snugly.
- Reattach the housing cover securely.

4. Fuel System Inspection

Inspect Fuel Injectors
- Visually check for leaks or damage.
- If necessary, use a fuel injector cleaner and follow the instructions on the product.
Check Fuel Pump
- Access the fuel pump (usually located in the fuel tank).
- Test the fuel pump pressure with a fuel pressure gauge to ensure it meets specifications.

5. Driving Habits and Maintenance

Encourage regular maintenance intervals, such as oil changes and fluid checks.
Suggest using cruise control on highways to maintain steady speeds.
Recommend avoiding excessive idling and aggressive acceleration.
