Why does my Ford Mondeo's engine make a strange noise?

I've noticed that my Ford Mondeo's engine has started making a strange noise when I accelerate. It's not a constant noise, but it comes and goes. What could be causing this and how can I fix it?

Hi Samantha, the strange noise could be caused by a number of things. It could be an issue with the ignition system, fuel system, or even a loose component in the engine. The best course of action would be to take your car to a trusted mechanic for a thorough inspection.

I had a similar issue with my Ford Mondeo's engine and it turned out to be a faulty spark plug. I would recommend checking your spark plugs and replacing them if necessary.

Another possibility is that the noise is coming from a worn out belt in your engine. The belt may need to be replaced in order to stop the noise.
