Why is my Ford Fiesta engine making a strange noise?

I've noticed that my Ford Fiesta's engine is making a strange noise. It sounds like a rattling or tapping noise when the car is idling. What could be causing this and how can I fix it?

It's possible that the noise is coming from a faulty or loose component in the engine. You should take your car to a mechanic to have it checked and repaired if necessary. It's always better to be safe than sorry when it comes to car troubles.

Another possible cause of the noise could be low engine oil. Check your oil levels and top up if needed. If the noise persists, it's best to have a professional take a look to rule out any potential issues.

One more thing to consider is the type of fuel you're using. If you've recently switched to a lower quality or ethanol blend, this could be causing the noise. Stick to using high-quality fuel for your Fiesta.
