Issue: Engine Running Rough in 2012 Volvo XC60

Repair Instructions

Replace Faulty Components
- If any issues are found during diagnostics (e.g., faulty spark plugs, fuel injectors, vacuum leaks), replace them according to the manufacturer's specifications.
Clean or Replace Air Filter
- If the air filter is dirty, replace it with a new one. Ensure proper sealing when installed.
Fuel System Cleaning
- If fuel injectors are clogged, consider using a fuel injector cleaning solution or replacing them if necessary.
Reassemble and Test
- After addressing all noted issues, reassemble any components that were removed.
- Start the engine and observe if the rough running condition persists.
Clear Codes
- Use the OBD-II scanner to clear any trouble codes and take the vehicle for a test drive to ensure that the check engine light does not reappear and the engine runs smoothly.

Conclusion

If after following these steps the engine is still running rough, it may be necessary to consult with a professional technician for further diagnosis, as the issue could be more complex (e.g., internal engine problems).
