I am not positive about a lot yet... I know the O2 sensor is new, so I have removed that from the list of variables.
I will set the CO with the AFM (now that I know where to work). And use that to remove a couple more variables.
The plugs look new per the PO's statement. (though showing rich issue of course).
And the spark wires are new, with a new rotor.
Concurrently, I am cleaning the fuel system. First with a Lucas treatment, and now Techron (separate fillings) with Chevron 91 being used as the fuel. I am planning on seafoaming her as well and have new Oil and a new Mahle filter waiting for her immediately following.
I am almost certain I can expect (just my luck) to replace the Cat as well, I just need to give the cat a chance... right now it's hardly a fair fight
Again, thanks for all of the input and advice. I am still having fun, but would really like to be able to register (and restore) this car.
