Is the number 3 wire arcing or grounding out anywhere? Is it loose on the plug itself?
My car was missing like crazy and I couldn't figure out why. I was playing around under the hood one day and noticed the boots were loose on the plug. Swapped the wires and it's been good, except for the miss at exactly 2600 RPM's cruising speed

try replacing the wire too. that will rule out the ignition systme at this point (coil/plug/wire). try just swaping the wire to a nother cylinder and see of the skip follows. if your sure the plug is good, then at this point if the skip doesnt change its problem fuel or compression related.

It may be as simple as a fouled out plug if you didn't change them during the swap. Try the Autolite plugs next time. I've had nothing but good things to say about them and they are only $2.50 each.
