Solution

1. Preparation

Gather tools and materials required for the repairs.
Disconnect the vehicle's battery to ensure safety while working on electrical components.
Ensure the vehicle is on a level surface and properly supported.

2. Inspect and Replace Faulty Components

Use the OBD-II scanner to identify specific fault codes.
Air Filter Replacement:
- Remove the engine cover if necessary.
- Remove the air intake duct.
- Replace the air filter with a new one, ensuring it is seated properly.
Spark Plug Inspection:
- Remove spark plug wires (label them for reinstallation).
- Use a spark plug socket to remove each spark plug and inspect for wear.
- Replace worn spark plugs with new ones, using the manufacturer-recommended gap.

3. Addressing the Gas Cap

Inspect the gas cap for cracks, wear, or damage.
If damaged, replace the gas cap with an OEM part.
Ensure the cap is tightened properly to the specified torque.

4. Clear Error Codes

Reconnect the battery and use the OBD-II scanner to clear any stored error codes.
Perform a test drive to see if the engine light remains off.
