Ran some more logs. Car starts up idling almost normal and then after 30 seconds or so starts the rough idle and misfire again. Same behavior as when I started it up last night and ONLY cylinder 3 misfire this time. All wires look good. Barely any wires on passenger side.

I did unplug but then replugged the o2 sensors at the firewall. Was not sure the proper diagnosis procedure, start with them unplugged or unplug one at at time or … Trying to minimize run time because once it starts misfiring it will inevitably start to die out (RPMs keep falling until it more or less feels like it will stall out. I turn it off before this has happened)
I did not inspect the crank trigger but that sounds much better than the tone ring!
Killing me that it is just a cylinder 3 misfire code, still! One suggestion was to keep starting it up and letting it run while the idle feels/sounds good and then shut it off when it starts to get rough. Try to cycle some of the old fuel out of the lines. This sounds good as anything I suppose. Is there a way to test the alternator without load or driving? The idling voltage seemed good but I dont know why the misfire takes a little bit to happen
