Why is the Ford Focus losing power?

I've been noticing a decrease in the acceleration and overall power of my Ford Focus. Is this a common issue? What could be causing it?

It's possible that your air filter may be clogged, reducing air flow and causing a decrease in power. I would recommend checking and replacing your air filter if necessary.

Another potential issue could be a faulty fuel pump or fuel filter. I would suggest getting these components inspected and replaced if needed.

It's possible that the engine's spark plugs may be worn out or dirty, causing a decrease in power. I would recommend getting them replaced as well.
