3. Address Identified Issues

If misfire codes are present:
1. Remove the ignition coils using a socket set.
2. Inspect and replace any faulty ignition coils as necessary.
3. Replace spark plugs if they show signs of wear (gap them to manufacturer specifications).
If fuel system codes are present:
1. Inspect fuel injectors for clogs; clean or replace as needed.
2. Check fuel pressure using a fuel pressure gauge; compare with manufacturer specifications.
If air intake issues are found:
1. Remove the air filter housing.
2. Replace the air filter if dirty.
3. Check the Mass Air Flow (MAF) sensor; clean it with MAF cleaner if necessary.

4. Clear Error Codes

After repairs are made, reconnect the OBD-II scanner.
Select the option to clear the error codes from the vehicle’s computer.

5. Test Drive

Start the engine and take the vehicle for a test drive to ensure the issue is resolved and monitor for any reoccurrence of the check engine light.
