#4 Cylinder Misfire

#4 Cylinder Misfire
I have a misfire on the #4 cylinder, I have changed the Spark Plugs, The Plug Wires, The Rotor & Distributor Cap. But I still seem to have the miss. If it is the #4 injector, how do I replace it. I swapped plug wires, & changed the Spark plug, what else could it be ? I forgot to mention it is a 1999 Suburban 4x4
thanks in Advance

The # 4 was kinda white, w/ a little black, it wasn't wet, I just took an old wire & replace the new one, I changed the new plug out with another new one but still have the misfire. I have an AutoEnginiuty program that I use, plus a generic scanner & they say the same, but what could be causining the misfire on #4?

Gotta remove the intake, that also means more than just injectors, but also gaskets. I looked on you tube for something to help, but nothing. I'd also add, replace all 8. You "may" have 1 bad, but going to this level, not replacing all of them just a matter of time befoer you'll be back into it.
