Why is my Kia Picanto revving on its own?

I have noticed that my Kia Picanto is revving on its own, even when I am not pressing the gas pedal. What could be causing this and how can I fix it?

It sounds like you might have a problem with your idle control valve. Take your car to a mechanic to get it checked and replaced if necessary. Also, make sure you are not resting your foot on the gas pedal while driving.

This could be caused by a faulty sensor or a clogged air filter. Have a professional check these components and replace them if needed.

If you recently filled up your tank, it could be a stuck fuel injector. Try using a fuel system cleaner or take your car to a mechanic for a more thorough cleaning.
