Why is my Kia ProCeed lacking power?

I've noticed that my Kia ProCeed is not performing as well as it used to. I have plenty of fuel and the engine seems to be running smoothly. What could be causing this issue and what steps should I take to fix it?

One potential cause for a lack of power in your Kia ProCeed could be a clogged air filter. It's important to regularly check and replace your air filter to ensure proper airflow to the engine. You could also check your spark plugs and make sure they are in good condition.

Another possible cause could be a problem with the fuel system. Make sure your fuel filter is not clogged and that your fuel pump is functioning properly. It's also a good idea to have a mechanic check the fuel injectors to see if they need to be cleaned or replaced.

If your Kia ProCeed has been running for a while without any maintenance, it's possible that the engine could be suffering from buildup of carbon deposits. Adding a fuel system cleaner to your gas tank could help remove these deposits and improve engine performance.
