Most of those people are trolls, sir. We don't let them get a rise out of us.
I did have to really rev it to get another car jump started, maybe that pushed out loose or non-bolting. Yes, a shop did the flex pipe and it was real quiet when it left. I should take it back there but it will cost me more in a day off than it will to leave it somewhere local so...
Holy moly, I assume that the PCM is seeing an unusable signal from the 02 sensor and it is defaulting into a mode where
it relies on other data to adjust fuel-trim.
I ran a Nissan farm truck without an O2 sensor for a very long time as the wiring was snagged and disconnected. It ran fine without it and I always thought that it defaulted to a certain spec based on the computer not receiving a signal. I hooked the wiring back up eventually and it seemed run about the same.
ALL cars and trucks as of 1991 had OBD 1 systems. That means that the POS you have has one, it just probably doesn't work....kinda like the rest of the car. OBD-2 was in full acceptance in 1995 by all car makers. You'll find some of the GM cars had it as early as 1993. That means that the junk you're working on has one although it's doubtful it works and is probably burnt out considering it's been on most likely for years. But I'll give you this, if you can drive it and do drive it, yer a brave soul. I wouldn't get in it sitting still and damn sure wouldn't ride in it.

1991 Honda had a cpu that blinked a trouble code. If you counted 16 blinks, it was a fuel injector problem. Pull a fuse in the engine bay for 10 seconds to clear the code.
Even after the explanation, i'm still with the poster who said it was staged.. While OP might have discovered it like that.. It did not get that way by itself. It was touched.. "staged" might be a little harsh, but.. That isn't a 'natural' failure.
And right now, some mechanic who has just finished using a can of penetrating oil and still snapped an O2 sensor off trying to replace it is screaming at the top of his lungs seeing that pic.

I dont think anyone believes it’s a “natural failure”. It’s either staged or someone did not bolt it back in.

Well then, that's easy! Has to not have been bolted back in, because I never touched that thing except after it fell out (-and was dragging on the ground for a block or two) to do this:
And CEL came on yesterday. Sure looks like an OBD2 CEL light...
