Why is the Ford Focus engine making a strange noise?

I recently bought a used 2017 Ford Focus and now the engine is making a strange noise. It only happens when I accelerate and it sounds like a rattling or clinking noise. What could be causing this and how can I fix it?

It's possible that there could be an issue with the timing belt or the engine mount. I would suggest getting it checked out by a mechanic as soon as possible.

Check the oil level and make sure it's at the recommended level. Low oil can sometimes cause strange engine noises. If the oil is fine, then it could be a problem with the exhaust system.

I had a similar issue with my Ford Focus and it turned out to be a faulty fuel pump. Get it checked by a mechanic and they can replace it if needed.
