Ford Expedition loud engine knocking and hesitation to drive with rough idle issues on Ford Expedition

Some Ford Expedition owners report experiencing loud engine knocking, which may indicate internal damage or issues with engine components. Additionally, these owners often face hesitation while driving, potentially linked to common transmission problems that require costly repairs. Rough idle is another concern, often signaling issues with fuel delivery, spark plugs, or overall engine health. The appearance of the check engine light after experiencing hesitation or stalling may suggest a failing mass airflow sensor. Furthermore, spark plug problems, such as fastening issues or sticking in the engine head, can exacerbate rough idling and engine performance. Some owners of specific model years, like the 2016 Ford Expedition, have noted poor fuel efficiency and persistent engine problems, leading to an overall rough driving experience. To effectively address these issues, it is recommended that owners have their vehicles inspected by a qualified mechanic for a proper diagnosis and timely maintenance.
