Why doesn't my Kia Stonic accelerate smoothly?

I recently purchased a Kia Stonic and I've noticed that when I press on the gas pedal, the car doesn't accelerate smoothly. It feels like it hesitates before finally speeding up. What could be causing this issue?

It's possible that there could be an issue with your fuel system. I would recommend taking it to a certified mechanic to have them check it out.

Have you checked your air filters? Dirty air filters can sometimes cause a delay in acceleration. It's an easy fix, so I would suggest trying that first before taking it to a mechanic.

I also have a Kia Stonic and I've experienced the same issue. After doing some research, I found out that it could be caused by a faulty throttle position sensor. You may want to have that checked.
