Solution

1. Preparation

Gather tools: OBD-II scanner, socket set, torque wrench, multimeter, and basic hand tools.
Disconnect the vehicle battery to ensure safety while working on electrical components.

2. Address Error Codes

Use the OBD-II scanner to retrieve and document error codes.
Research each code to determine the likely cause and necessary repairs.

3. Inspect and Replace Spark Plugs

Remove the ignition coil covers and disconnect the electrical connectors.
Unbolt and remove the ignition coils.
Use a socket to remove the spark plugs; inspect for wear or deposits.
Replace with new spark plugs, torqued to manufacturer specifications (usually around 13-15 ft-lbs).

4. Check and Replace Air Filter

Locate the air filter housing and unclip or unbolt the cover.
Remove the old air filter and inspect the housing for debris.
Install a new air filter, ensuring a snug fit.

5. Inspect Fuel System

Check for fuel leaks by inspecting the fuel lines and injectors.
If leaks are found, replace the faulty components.
Use a fuel pressure gauge to test fuel pressure; replace the fuel pump if pressure is low.

6. Clear Error Codes

Reconnect the battery and use the OBD-II scanner to clear the error codes.
Monitor the check engine light to verify it remains off after repairs.
