What are the most common causes of rough idling in a Kia Rio?

I've been experiencing rough idling in my Kia Rio and it's starting to worry me. Can you give me some insight into what could be causing this issue?

The most common cause of rough idling in a Kia Rio is a dirty fuel injector. It's important to have your fuel injector cleaned and inspected regularly to prevent this issue.

Another potential cause of rough idling could be a faulty ignition coil. In this case, it's best to have a professional mechanic diagnose and replace the faulty part.

Low engine oil levels can also contribute to rough idling in a Kia Rio. Make sure to check and change your oil regularly to keep your engine running smoothly.

A clogged air filter can also be the culprit behind rough idling. It's a good idea to replace your air filter every 12,000 miles to keep your engine running efficiently.
