04 Disco misfires

Hey guys. I have an 04 Disco with #1 and #6 misfires. I replaced the coils, wires and plugs (the wires and plugs were old so I did them while I was there). The drivers side coil has #1 and #6 in the same pack, so I thought for sure this was the issue....have seen it on many other cars before. After replacement, the misfire codes are still coming back.

Also I am getting a P0414 code (optical sensor open or short). Does anyone know what that sensor is/where that sensor is?

Thanks is advance for the help
