Switch the wires on the cylinder that has the misfire, see if that moves the missfire, if it does then you might have a bad wire.

miss fire happened before i changed the wires. brand new wires.

No, I'm saying if you have a misfire on #1, switch that wire to #3 and see if you get a misfire on #3. If you do, then you know it's related to the sparkplug wire, or coil.
