Why does my Ford Fiesta make a rattling noise when I accelerate?

I recently noticed that my Ford Fiesta has been making a loud rattling noise whenever I accelerate. It seems to come from the engine area and the noise gets louder as I drive faster. What could be causing this and should I be worried?

It's possible that the rattling noise is coming from a loose component in the engine, such as a heat shield or exhaust hanger. You should have it checked by a mechanic to make sure it's not a more serious issue.

This could also be caused by a problem with the ignition timing or a dirty fuel filter. I would recommend taking your Ford Fiesta to a trusted mechanic for a diagnostic test.

I had a similar issue with my Ford Fiesta and it turned out to be a loose air intake hose. You may want to check all the hoses and connections under the hood to see if any need to be tightened.
