What causes a Ford Focus to lose power while driving?

I have a 2012 Ford Focus and recently it's been losing power while driving. The engine light has also been on. What could be causing this issue and how can I fix it?

It's possible that your fuel filter or spark plugs may need to be replaced. You should also check your air filter and make sure it's not clogged.

Another common issue with Ford Focuses is a faulty throttle body. This can cause loss of power and the engine light to come on. I would recommend getting it checked and possibly replaced.
