Why does my Kia Rio's engine seem to be misfiring?

Recently, my Kia Rio's engine has been running rough and seems to be misfiring. It's affecting the performance of my car and I'm not sure what's causing it. Can anyone provide some advice on what could be causing this issue and how I can fix it?

It sounds like your Kia Rio may be experiencing a spark plug issue. Have you checked them recently? Sometimes they can become dirty or worn, causing misfires.

I had this same issue with my Kia Rio last month and it turned out to be a faulty fuel injector. I would recommend getting it checked by a mechanic if cleaning or replacing the spark plugs doesn't solve the issue.

Make sure to also check your air filter and replace it if it's dirty. A clogged air filter can also cause misfiring in your Kia Rio's engine.
