Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, multimeter, torque wrench, replacement parts as necessary.
Disconnect the battery to ensure safety while working on electrical components.
Allow the engine to cool down before performing any inspections.

2. Address Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Retrieve and document the stored trouble codes.
Research the specific codes to pinpoint areas for further inspection or repair.

3. Inspect and Replace Components

A. Gas Cap

Sub-steps:
- Remove the gas cap and inspect for cracks or wear.
- Replace with a new gas cap if damage is found.
- Tighten the gas cap securely before starting the engine.

B. Spark Plugs

Sub-steps:
- Remove ignition coil or plug wire to access spark plugs.
- Use a socket to remove the spark plugs.
- Inspect for wear; replace if necessary (recommended gap is typically 0.8mm).
- Reinstall new plugs to manufacturer specifications (usually around 15 ft-lbs).

C. Air Filter

Sub-steps:
- Locate and remove the air filter housing.
- Take out the old air filter and inspect for dirt.
- Install a new air filter, ensuring it fits snugly into the housing.

4. Battery and Alternator Testing

Sub-steps:
- Use a multimeter to check the battery voltage (should read around 12.6 volts).
- Start the engine and check voltage again (should be between 13.7 to 14.7 volts).
- If readings are outside this range, consider replacing the battery or alternator.
