Were the spark plug wires replaced? Even a pinhole in a plug wire can leak enough spark to cause a misfire. Try swapping that wire with another similar length wire from another plug and see where the misfire is then. If the misfire moves to the new cylinder or ceases completely, you'll know the wire was bad.
