Why is the acceleration in my Kia Sportage not as strong as before?

I've noticed that the acceleration in my Kia Sportage has not been as strong as it used to be. What could be causing this issue and how can I fix it?

It could be due to a clogged air filter. I recommend checking and replacing the air filter if necessary. This is a simple and affordable fix that can greatly improve your acceleration.

Another possible cause could be a faulty spark plug. I suggest getting your spark plugs inspected and replaced if needed. This will help improve your engine's performance and therefore, your acceleration.

Low fuel pressure can also impact acceleration. Have a mechanic check your fuel pressure and fuel injectors. This can help determine if there are any issues that need to be addressed.
