How do I improve the performance of my Ford Fiesta engine?

I've noticed that my Ford Fiesta's engine seems to be struggling a bit, especially when accelerating. What can I do to improve its performance?

It could be a number of things causing this issue. It's always a good idea to start by checking your air filter and replacing it if it's dirty. A clogged air filter can reduce your engine's performance. You could also try adding a fuel injector cleaner to your gas tank.

Another potential cause could be a dirty or failing spark plug. If you haven't replaced your spark plugs in a while, it may be time to do so. You could also take your car to a mechanic for a diagnostic test to pinpoint the exact issue.
