What are the common problems with Ford Mondeo's engine?

I recently purchased a Ford Mondeo and I have been experiencing some issues with the engine. It makes a strange noise when starting the car and it seems to be running rough sometimes. What could be the potential causes and how can I fix it?

It sounds like you may have an issue with your spark plugs. They may need to be replaced or they could just need to be cleaned. This is a common problem with Ford Mondeos and can easily be fixed by a mechanic.

Another potential cause could be a clogged fuel injector. This can lead to rough running and the strange noise you are hearing. It's important to have this checked and cleaned as it can cause damage to the engine if left untreated.
