How to fix engine misfire in a Ford S-Max?

I've been noticing that my Ford S-Max has been experiencing an engine misfire. The engine seems to be running rough and the check engine light is on. What could be causing this issue and how can I fix it?

One potential cause of engine misfire could be faulty spark plugs. Try replacing them and see if it improves the performance of your car.

Another possible reason for engine misfire could be a dirty fuel injector. Consider getting it cleaned or replaced if necessary.

Low fuel pressure or a clogged fuel filter could also lead to engine misfire. Have a mechanic check these components and replace them if needed.
