P0306 loss of power. NEED Help

Having 3 new codes coming up. P0306-misfire on cylinder 6, p0158, p2272.

Use my truck as a daily driver for work. Driving along before 80km/h is not to bad but can still feel a little loss of power. If i step down on gas the truck has no power and sounds like maybe cat converter is plugged. If truck is pushed to limit she will make it to her 4000 rpm and will change her gears. So i'm just glad its not tranny. Need help daily driver.

My first step would be to either just replace the number six coil or switch it with another to see if the misfire follows the coil. Have the plugs ever been changed? If so were the coil boots replaced and new motorcraft plugs used? Many times if the convertor is damaged you can hit it with a rubber mallet and hear the broken pieces in it rattle around in there.

Both of the other codes refer to the downstream bank two oxygen sensor. Might check for a bare wire or major exhaust leak in that area.
