Why does my Ford S-Max experience engine misfires?

I recently purchased a used Ford S-Max and have been experiencing engine misfires while driving. The issue seems to occur randomly and I'm not sure what could be causing it. Can anyone provide some insight or tips on how to fix this issue?

Hello Bethany, it sounds like your Ford S-Max may have a faulty spark plug or ignition coil. I recommend taking it to a certified mechanic to have them diagnose and replace any necessary parts.

Hi Bethany, engine misfires can also be caused by dirty fuel injectors or a clogged air filter. I suggest having these components checked and cleaned to see if that resolves the issue.

Hello Bethany, another common cause of engine misfires in Ford S-Max is a malfunctioning oxygen sensor. I recommend having this sensor tested and replaced if necessary.
