Full Bank Misfire ?

Full Bank Misfire ?
Good day everyone, I did a search and wasn't able to find anything concrete so I figured I would try crowd sourcing an answer or atleast get some ideas out of you guys.
The vehicle in question is a 2003 Land Rover Discovery II (North American) 4.6L V8.
Cylinders 1,3,5,7 (driver side) are all misfiring. When I did a search I found that possibly there is oil in the Crank position sensor shorting it out, or possibly MAF ?
It was fine up until about a week ago, is Land Rover known for bad grounds(corrosion) ?
Thanks for your help I look forward to talking with you, if there anymore information that you need or photos just let me know.
**Edit**
I believe I should add this pertinent information to save some questions in the future. This engine was rebuilt about 8000km ago, part of that included new plugs, wires, coils and crank position sensor along with 4 new o2 sensors.

Considering the amount of time since the rebuild hopefully the connector just wasn't fully seated and it wiggled loose rather than just bad timing on the coil failing. It can be done without removing intake but it's tight so getting back there with gloves would be tough. Good luck.

And this is a new one that wasn't there before...
P0134 which is strange, this is bank 1 sensor 1 theoretically the cause of the problem. Not sure why it wasn't there before, but also... Listen to this, I was about to live stream data from this o2 sensor showing its in the right voltage range 🤷♂️ any thoughts on that ?

good catch, totally had a major brain fart at work when I typed my response. My bad North, that was some bad advice.
