Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, and screwdrivers.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to reset the system if necessary.

2. Addressing Error Codes

Connect the OBD-II scanner to the vehicle's diagnostic port.
Turn on the ignition to the "ON" position without starting the engine.
Retrieve and record the diagnostic trouble codes (DTCs).
Research the DTCs to identify the specific issue.
For common issues like oxygen sensor failure, replace the faulty component according to manufacturer specifications.

3. Inspecting Components

Fuel Cap Check
- Remove the fuel cap and inspect for cracks or damage.
- Reinstall tightly and clear codes if necessary.
Spark Plug Replacement
- Remove ignition coils using a socket set.
- Extract spark plugs using a spark plug socket.
- Inspect for wear; replace if necessary with OEM specifications (typically 0.028 in gap).
- Reinstall the new spark plugs and coils.
Air Filter Replacement
- Open the air intake housing using screwdrivers.
- Remove the old air filter and inspect for dirt.
- Install a new air filter, ensuring it fits snugly.

4. Final Steps

Reconnect the battery terminals securely.
Clear any error codes using the OBD-II scanner.
Start the engine and allow it to reach operating temperature.
Monitor for any unusual noises or warning lights.
