Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a flat, stable surface.
Disconnect the battery before beginning any electrical work.

2. Address Error Codes

Use the OBD-II scanner to retrieve and document the trouble codes.
Based on the codes, research specific components associated with the issues indicated.

3. Repair or Replace Faulty Components

Gas Cap: If the gas cap is found to be faulty, replace it with an OEM or manufacturer-recommended part.
Air Filter: If the air filter is dirty, remove the old one and replace it with a new, clean air filter.
Ignition System: If the spark plugs or ignition coils are worn, remove them using a socket wrench, and replace with new, recommended components. Torque spark plugs to manufacturer specifications (typically around 15-20 Nm).

4. Reset the Check Engine Light

After repairs, reconnect the battery and use the OBD-II scanner to clear the error codes.
Start the engine and allow it to idle, ensuring no new codes appear.
