Why is my Kia Soul's engine idling rough?

I've noticed that my Kia Soul's engine is not running as smoothly as it used to. It sometimes idles rough and has a slight vibration. What could be causing this and how can I fix it?

Low levels of engine oil or dirty oil can also contribute to rough idling. Make sure to regularly check and change your oil to keep your engine running smoothly.

Have you recently changed your air filter? A dirty or clogged air filter can also affect engine performance and cause rough idling. Consider replacing your air filter to see if it improves the issue.

If none of these solutions fix the issue, it may be a more serious problem with the engine. I recommend taking your Kia Soul to a certified mechanic for a diagnosis and proper repairs.

There could be a few reasons for this, but the most common cause is a dirty or clogged fuel injector. This can cause uneven fuel distribution and lead to rough idling. I would recommend getting your fuel injector cleaned or replaced.

Another possible cause could be a problem with your spark plugs. If they are dirty or worn out, they can misfire and cause vibrations in the engine. I suggest checking and replacing your spark plugs if needed.
