What are the common issues with the Ford Fiesta's engine?

I've been experiencing some problems with my Ford Fiesta's engine lately. Can anyone suggest what might be causing it and how to fix it?

One common issue with Ford Fiesta's engine is overheating, which can be caused by a faulty radiator or coolant system. Check for any leaks and make sure to replace any damaged parts.

Another issue could be with the spark plugs, which may need to be replaced if the engine is misfiring or idling rough. It's usually a simple fix and can improve the overall performance of the car.

If you notice a decrease in power and acceleration, it could be due to a dirty air filter. Try replacing it and see if it improves the performance of your Ford Fiesta.
