7. Check the compression: Perform a compression test on all cylinders to ensure there are no internal engine issues causing the misfire.

8. Inspect the intake and exhaust systems: Check for any vacuum leaks, clogged air filters, or restrictions in the exhaust system that may affect combustion.

9. Reset the error code: After addressing the underlying issue, use the OBD-II scanner to clear the misfire code. Take the vehicle for a test drive to ensure the issue is resolved.

If the misfire persists after following these steps, it is recommended to consult a professional mechanic for further diagnosis and repair.
