Solution

1. Preparation

Gather necessary tools and parts: OBD-II scanner, tire pressure gauge, air filter, spark plugs, fuel injector cleaner.
Ensure the vehicle is parked on a level surface and the engine is cool before beginning work.

2. Tire Maintenance

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure of each tire.
- Inflate tires to the recommended PSI found in the owner's manual or on the driver's door jamb.
Inspect Tire Condition:
- Look for uneven wear or damage; replace tires if necessary.

3. Air Filter Replacement

Remove the Air Filter:
- Open the engine cover and locate the air filter housing.
- Unclip or unscrew the housing and remove the old air filter.
Install New Air Filter:
- Place the new air filter into the housing and secure it back in place.

4. Spark Plug Inspection and Replacement

Remove Old Spark Plugs:
- Disconnect the battery.
- Use a spark plug socket to remove each spark plug.
Install New Spark Plugs:
- Check the gap on each new spark plug using a feeler gauge.
- Install the new spark plugs, tightening them to the manufacturer's torque specification (typically 15-20 lb-ft).

5. Fuel Injector Cleaning

Use Fuel Injector Cleaner:
- Add a quality fuel injector cleaner to the fuel tank as per the manufacturer's instructions.
- Drive the vehicle for a few hundred miles to allow the cleaner to work through the system.

6. Driving Habit Modification

Assess and Adjust Driving Habits:
- Encourage smoother acceleration and braking.
- Reduce idling time and avoid aggressive driving.
