Why does my Ford Focus produce a rattling noise under the hood?

I recently noticed that my Ford Focus is producing a rattling noise whenever I accelerate or decelerate. It seems to be coming from under the hood but I can't pinpoint the exact location. Any idea what could be causing this and how to fix it?

It sounds like you may have an issue with your engine or exhaust system. It's best to have a mechanic take a look at it to properly diagnose and fix the problem.

I had a similar issue with my Ford Focus and it turned out to be loose or damaged heat shields. Have your mechanic check those as well.
