Why is the acceleration on my Ford Puma not as strong as it used to be?

I have noticed that the acceleration on my Ford Puma has become noticeably weaker over time. I used to be able to easily overtake other cars, but now I struggle to keep up with traffic. What could be causing this and how can I improve my car's performance?

This could be due to several factors, such as worn spark plugs or a dirty air filter. To improve performance, you can try replacing these parts and see if that makes a difference.

Another possible cause could be a clogged fuel filter. As a general rule, it's recommended to replace the fuel filter every 10,000-15,000 miles to ensure optimal engine performance.
