Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Disconnect the battery before starting work on electrical components.

2. Replace Air Filter

Remove the air filter housing cover using a socket set.
Take out the old air filter and inspect the housing for debris.
Install a new air filter, ensuring it fits securely.
Reattach the housing cover and tighten the screws.

3. Clean Fuel Injectors

Remove the fuel rail assembly as per service manual instructions.
Disconnect the fuel lines carefully to avoid fuel spillage.
Use a fuel injector cleaning kit to clean the injectors.
Reinstall the fuel injectors and ensure they are seated properly.

4. Replace Spark Plugs

Remove the ignition coil or spark plug wires using a socket set.
Unscrew the old spark plugs and inspect for wear.
Install new spark plugs, ensuring the gap is set to manufacturer specifications (usually around 0.043 inches).
Reinstall the ignition coils or spark plug wires.

5. Check Tire Pressure

Use a tire pressure gauge to check each tire.
Inflate tires to the recommended pressure (usually found on the driver’s door jamb).
Inspect tires for signs of uneven wear and replace if necessary.
