Why is my Ford Mondeo shaking while idling?

I recently purchased a used Ford Mondeo and have noticed that it shakes while idling. What could be causing this and how can I fix it?

One possible cause could be dirty fuel injectors. Try using a fuel injector cleaner or have them professionally cleaned.

Another reason could be a problem with the engine mounts. If they are worn or damaged, it can cause shaking while idling. Have them checked by a mechanic.

Low oil levels can also lead to shaking while idling. Check your oil level and top it off if needed.

It's also possible that the spark plugs need to be replaced. Old or dirty spark plugs can cause an engine to shake.
