Why is my Ford Focus shaking while idling?

I recently purchased a used Ford Focus and noticed that it shakes quite a bit while idling. Is this something I should be concerned about? What could be causing this issue and what steps should I take to fix it?

This shaking could be due to a few different factors, such as worn out spark plugs or a dirty air filter. I would recommend bringing your car to a trusted mechanic to diagnose the issue.

I experienced the same issue with my Ford Focus and it turned out to be a problem with the engine mounts. I had them replaced and now the shaking is completely gone. I would suggest getting those checked.
