Well, I re-routed #5 and #7 spark plugs at the suggestion of someone on
the MML and went to a colder plug and that reduced it to a couple light
pings just before it shifts out of 1st at around 5200rpm.
The O2 sensor is on my list of things to replace, I have one sitting in
a box, but it looks like a PITA to do so I think I might make some poor
schlub at a shop do it. ;)
The plugs were pretty dang white when I pulled them:

I went from NGK FR4 to NGK zfr6f-11. You'd think two ranges colder
would be excessive but this is what's recommended for 97+ 5.2L and 5.9L
Ram/Dakotas from what NGK.com says.
We'll see, I have a spare intake manifold in my closet with the pan
replaced with Hughes-style aluminum plate if it comes down to it.
Thanks,
M.B.
