Question about 2003 Kia Rio
You didn't mention the mileage, but you should consult the owners manual & see if any tune-up maintenance may be due. Additionally, the air filter, fuel filter, fuel injectors, spark plugs as well as a few other items can cause hesitation on acceleration.
If there are no engine warning lights, you could also try a little fuel injector cleaner (available at your local auto parts store & most larger auto departments of places like Walmart) I always get the 3.00 a bottle gumout cleaner, use 1 bottle for a 1/2 tank, repeat in about a week & see if that doesn't help. good luck
