If you notice rough running after air-filter service, capture the exact conditions instead of relying on “it happens sometimes.” Note whether the engine began running differently right after the filter was replaced. Save the date, mileage, and any warning message.
Repeatable notes help a technician reproduce the concern and distinguish a one-off event from a pattern. Check that the airbox is closed and intake duct or sensor connectors are fully seated.
Quick educational note
For information, not a diagnosis or repair instruction. Vehicle-specific checks are still required. Consult the manufacturer's guidance and a qualified technician.
