Running a bit rough. Doesn't stall, but when stepping on the gas it will sputter

(2001 Mazda B3000)
in Stillwater, MN on December 08, 2012
Check engine light comes on. Got that checked. Code meant a problem with #3 cylinder. Replaced that spark plug and got a new set of wires put in. Yet the sputtering remains. Not sure what to try next. Even check the air in-flow and it looks clean. What do you think?

What did the spark plug that you replaced look like? That info would help point a direction , if indeed it was a problem (presume DTC P0303).
