Stft's went right back to a few percent here or there. I'm still not sure what happened, it had never happened before and hasn't happened again.

Got home put the MSD wires back on. Before starting it I did the stft reset with the key on. Fired it up and could tell right away it was running better and lamda was sticking right around 1.0, where yesterday it was hanging around 1.3.
Was just going to move it over to the other side of the garage but backing out it was acting like it was back to normal so I took it around the block and everything from idle to a gentle pull was great. Even idled great for 5 minutes when I got back.
So WTF is this thing just messing with me? I do have before and after logs if anyone wants to look at them to help me figure out what is going on.
Thanks for the winning suggestion JLAudio11.
