Why is my Kia Rio experiencing a loss of power?

I recently purchased a used Kia Rio and have noticed a significant loss of power while driving. What could be causing this and how can I fix it?

The loss of power could be due to a clogged fuel filter or a faulty oxygen sensor. I suggest getting those checked and replaced if needed.

Another possibility could be a leaking or damaged exhaust system. This can cause a decrease in engine power. I recommend taking your Kia Rio to a mechanic for a thorough inspection.

Make sure to regularly check and change your spark plugs as they can wear out over time and affect the performance of your engine. Consider replacing them if they are old or dirty.
