Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery to prevent any electrical issues.

2. Fuel System Inspection

Check for leaks:
- Inspect all fuel lines and connections visually.
- Use a fuel pressure gauge to test the fuel system's pressure.
Clean fuel injectors:
- Remove the fuel injectors using a socket set.
- Clean injectors using a dedicated fuel injector cleaner or ultrasonic cleaner.
- Reinstall injectors and ensure secure connections.

3. Air Filter Replacement

Locate the air filter housing.
Remove the air filter cover using a screwdriver or socket set.
Take out the old air filter and replace it with a new one, ensuring a snug fit.
Reattach the air filter cover securely.

4. Spark Plug Replacement

Remove the ignition coils using a socket set, if applicable.
Extract old spark plugs with a spark plug socket and inspect for wear.
Install new spark plugs, ensuring the correct torque (typically around 15-20 ft-lbs).
Reattach the ignition coils securely.

5. Tire Pressure Check

Use a tire pressure gauge to check each tire's pressure.
Inflate tires to the manufacturer's recommended pressure, usually found on the driver’s door jamb label.

6. Exhaust System Inspection

Visually inspect the exhaust system for any visible holes or rust.
If blockages are suspected, use a smoke test to identify leaks.
Repair or replace any faulty exhaust components as needed.
