Why does my Kia Ceed's engine shake at idle?

I recently purchased a used Kia Ceed and noticed that the engine shakes when the car is idling. What could be causing this and how can I fix it?

There are a few potential reasons for this issue. Firstly, it could be due to spark plug issues, so it may be worth getting them inspected and replaced if necessary.

Another possibility is an issue with the fuel injectors. They may be dirty or clogged, causing the engine to shake. Try using a fuel injector cleaner to see if that helps.

It could also be a problem with the engine mounts. Over time, they can wear out and cause the engine to vibrate. Have a mechanic check and replace them if needed.
