Possible issues with the engine in a Kia Sorento

My Kia Sorento's engine seems to be making strange noises and is not performing as well as it used to. What could be causing these issues?

It is possible that there is an issue with the spark plugs or ignition coils. These should be checked and replaced if necessary.

Another possibility could be a clogged air filter. Try replacing the air filter and see if that improves engine performance.

If the engine is overheating, it could be due to a faulty thermostat. Get it checked and replaced if needed.

Make sure to regularly change the oil and oil filter to maintain optimal engine performance.
