What are common causes of a rough idle in a Kia Soul?

I recently purchased a Kia Soul and noticed that it has a rough idle when sitting at a stop light. What could be causing this and how can I fix it?

A rough idle in a Kia Soul can be caused by a few different factors. One common cause is dirty fuel injectors. Over time, carbon deposits can build up on the injectors and affect their performance. I would recommend trying a fuel system cleaner to see if that helps.

Another possible cause could be a faulty spark plug. If one or more of the spark plugs are worn or not working properly, it can lead to a rough idle. I suggest having a mechanic check and replace any bad spark plugs.

Low engine oil can also contribute to a rough idle in a Kia Soul. When the oil is low, it can cause the engine to run rough and create vibrations. Make sure to regularly check and top off your engine oil to prevent this issue.
