THROWING MISSFIRE CODE AND RUNS ROUGH.

1997 Chevrolet Silverado • 125,000 miles

I have a 97 Chevy z71 its throwing a missfire code on cylinder 3. Replaced plugs noticed 3 was black. Replaced, wires, cap, rotor, fuel pump and filter, still didn't help. Could this be the injector?

Is it a constant miss fire?
