Alright I’ve done everything I can now until my O2 sensors get her May 2nd once i install them I’ll update on what’s going on. I am unsure abt using the 2 old downstream sensors for the upstream and using my new 2 as the downstream because I’ve heard a lot of bad things about swapping them out.
The downstream sensors are the ones responsible for fueling trims. The upstream are only there as a check.
If the downstream are working and you’re getting codes for a failed upstream, the old, hardworking downstream sensors will now feel like they’re on easy street!

Why? What have you heard?

There is nothing unique about a sensor once its been installed...in any car. It doesn't wear a specific way, like perhaps a piston or a brake pad. It just senses hot gasses.

All four sensors are interchangeable. So interchangeable that there's a feature in the Jaguar diagnostic software that teaches the car how to figure out which sensor is which if the mechanic was to ever unplug all four at the same time and forget which plug goes where.

What was your Walker # for reference ?
I got a couple of spare O2 sensors and a MAF sensor from a X300 at a salvage yard
They have a tendency to cut the O2 sensors out and sell them to a precious metal ( platinum ) melter without knowing how special they are
They sell for 5 dollars US but they cut them out as soon as the donor car arrives at the salvage yard so you have to call
There is a way to test the salvaged O2 sensor off car including the suspect one you have

Yesterday I replaced the upstream switch the 2 new ones I got and drove around. Then today I disconnected the battery for a while to reset everything and I got new engine codes
P1187
P0152
P0132
not sure if the new sensors aren’t working properly or what may be going on, I’m thinking abt taking to a mechanic but any advice ?

Drive it a couple more cycles as things fully heat up and the ECU adjust to the new sensors
Make sure you erase them just before final 3 test drives , again some codes will not latch until 3 cycles after reset
Your codes start on page 121 , 1995 has it's own list starting page 110

Disconnecting the battery shouldn't do anything.
If you have an OBD2 reader, that would be the correct tool to delete the codes, not disconnecting the battery.
If you're trying to delete something else that affects the oxygen sensors, you're out of luck. The fuel trims get stored in RAM memory, so you could leave the car disconnected from a power source for twenty years and not change a thing.

hey would you happen to still have those Spare O2 sensors, the ones I got won’t turn the light off and I’m afraid because their aftermarket they may just not work

For instance, I had purchased Denso sensors one time, and they still carried an NTK stamp on them!

yes my bad forgot the 1 but yea those are it, I was talking tia mechanic and he was saying that a lot of times aftermarket O2 sensors won’t get picked up by the ECU because of how sensitive they are in older vehicles. I say all this because my check engine light is still on.

On top of that, there's no history on these boards with the ECU not "picking up" aftermarket oxygen sensors. I believe the OEM was Denso (made by NTK), but Bosch was probably the highest used replacement (aftermarket). I'm sure plenty of Wagners were used as well, without incident.
