WHY IS MY CAR SPUTTERING/STIMBLING WHEN DRIVING BETWEEN 2800 AND 3200 RPMS

2008 Kia Spectra • 55,000 miles

When I am driving at around 3000 rpms my car will intermittantly stumble or sputter. There is no noticable fluxuation in my rpms when this happens. There is nothing else that I have noticed to be wrong. Idiling seems fine as well as mpg. Checked plugs and they look really good. It somewhat unpredicatable but is doing is more and more no matter car temp or distance
