    You need to get the firing order to pin point the issue to a certain plug, but good rule of thumb is change the wires when you change the plugs. If this doesnt work change the coil.

    Swap the coil from #1 to #3 and see if the misfire follows the coil ,if it does , then replace the bad coil.
