Troubleshooting the Kia Stonic's Engine

I've been having issues with my Kia Stonic's engine, where it sometimes sputters and dies while idling. What could be causing this and how can I fix it?

It sounds like you could be experiencing a problem with your fuel system. Check your fuel filter and make sure it's not clogged. Also, try using a fuel system cleaner to see if that helps.

Another possibility is that your spark plugs could be worn out or faulty. Try replacing them and see if that improves the issue.

If neither of those solutions work, it could be a problem with your engine's sensors. Have a mechanic run a diagnostic test to see if any codes come up that could pinpoint the issue.
