If my other diagnosis do not work I will be heading down this route.

The two new ones I put in (part number 89465-69115) are not OEM/compatible? Would hate to toss more money on parts until I check out the other tips in the discussion.
You good!

Absolutely get that. Firing the parts cannon willy nilly isn’t advisable. BUT, if your issue ends up being related to the O2 sensors, I would stick with OEM. I’ve read of too many failures where aftermarket sensors are concerned. They (oem sensors) are still out there and available.
I think I have honed in on the issue. The connection wires for the O2 sensor are as shows, open wires frayed. Next question would be does anyone know where to get a new set of wires/connection?

I poked around a little, and found this thread... it covers that wiring (just scroll down a bit on the first page and you'll see the diagrams):
Wire to bank 1 O2 sensor corrupt 1994 FZJ80 help pleas
I read TIS FSM I have I used Search I cannot understand which wire connects to Bank 1 ? Is it engine wire 82121-60342? I fixed this 3 times already it works for a few mounts and then again it failed I am wondering if it is possible to take it out form rig and put it on the table to renew...

If only one of the wires is frayed, I would strip back the covering, solder in new wire and heat shrink a new cover on to it. Those wires have quite a bit of "play".
That sounds like the better idea! Thanks!I poked around a little, and found this thread... it covers that wiring (just scroll down a bit on the first page and you'll see the diagrams):

Which 02 sensor has these damaged wires? Curious how that could have happened?
look on the plastic housing for the connector number, seach for it in the wiring repair manual listed in the resources section of this forum and then find the corresponding repair wire to order from your dealer. or try Ballenger motorsport
On the sensor closer to the driver side, I had a similar thought as to how it could have happened. The covering over the wires has fell apart so I’m assuming a rock or some sort of debris whacked it good.
Copy that, I ordered a whole new connection housing and wires due to how rough it’s looking.

Just following up on the fix for my original issue!
I bought oem o2 sensors from toyota, they only had the passenger side sensor available so I bought two of them. after replacing them the idle issue is fully resolved.

Quick update, I replaced the connection housing and the troubled O2 sensor and the truck is running perfect again. Thanks everyone for the helpful advice!
just wanted to add 2 NTK 24080 o2 sensors worked for me. Plug and play. I had a code 21 with awful misfire and sluggish accel that was getting worse. The CEL went away after replacing the forward one. It still ran poor so replaced aft one as well. Now it runs better than I can remember. I also have them in the PAIR ports and still have a stock EGR set up
