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

I have been experiencing some problems with my Ford Fiesta's engine and I'm not sure what to do. I've noticed a decrease in performance and occasional strange noises. Can someone please advise me on the potential causes and best course of action?

It sounds like you may be dealing with a faulty fuel injector or spark plugs. It's important to get yourcar checked by a certified mechanic as soon as possible to avoid further damage to your engine.

Based on your description, it could also be an issue with your timing belt. This should be checked and replaced regularly to prevent any major damage to your engine.

I had a similar issue with my Ford Fiesta and it turned out to be a dirty air filter. It's a simple fix and can greatly improve the performance of your car.
