Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the negative terminal of the battery to prevent electrical shorts.
Allow the vehicle to cool down if the engine has been running.

2. Address Error Codes

Use the OBD-II scanner to read the error codes.
Research the codes to identify the specific problem areas.

3. Perform Necessary Repairs

If the issue is with the spark plugs:
- Remove the ignition coils using a socket set.
- Replace old spark plugs with new ones, torquing to manufacturer specifications (typically around 15-20 ft-lbs).
If the air filter is clogged:
- Open the air filter housing by removing screws or clips.
- Replace the old air filter with a new one.
If vacuum leaks are detected:
- Locate the damaged vacuum hoses.
- Replace any cracked or broken hoses with new ones.
If fuel system issues are present:
- Check the fuel pressure using a fuel pressure gauge.
- If pressure is low, inspect the fuel pump and filter for blockages or failures.

4. Reset the Check Engine Light

After completing repairs, reconnect the battery terminal.
Use the OBD-II scanner to clear the error codes.

5. Final Check

Ensure all components are reassembled properly.
