Why is my Ford Mondeo's engine making unusual noises?

I recently purchased a Ford Mondeo and I have noticed that the engine is making some strange noises. It's like a rattling sound when I accelerate. Is this something I should be concerned about? What could be causing it?

It's possible that there could be an issue with the spark plugs or the timing chain. I would recommend taking your car to a Ford dealership to have them check it out.

I had the same issue with my Ford Mondeo and it turned out to be a problem with the exhaust system. I would suggest taking it to a mechanic to get it checked.
