Why is my Kia Ceed's acceleration sluggish?

I've noticed that my Kia Ceed seems to have difficulty accelerating quickly, even after I've had it for a few years. What could be causing this and how can I improve the acceleration?

One possible reason for sluggish acceleration could be a dirty air filter. It's important to regularly clean or replace the air filter to ensure proper airflow and improve engine performance.

Another potential cause could be a clogged fuel filter. This can restrict the flow of fuel to the engine and result in poor acceleration. Consider getting the fuel filter checked and replaced if necessary.

It's also possible that a faulty oxygen sensor is causing the sluggish acceleration. This sensor helps regulate the air-fuel mixture in the engine, so if it's not working properly, your car's performance can suffer. Have a mechanic check the oxygen sensor and replace it if needed.
