Default My rear 02 Sensor got wet and my car never ran better!

I recently replaced my front 02 sensor finally only giving me a P0136 code of an 02 circuit malfunction on my rear sensor.

I have:

Borla Headers
Custom Track Pipe(No cats)
Apexi N1 cat-back

I drove in some rain and went through a HUGE puddle. Immediately, my car bogged and it did for another minute till it dried out underneath. Later that day, I cranked up my car and NO CEL! It was a miracle and my car was running great! Unfortunately, it came back and it's the same code.

I assume water temporarily killed my rear 02 and somehow erased the code.

Is there a way I can keep it that way? Do I need to replace the sensor? (it is currently unplugged and runs OK, but CEL remains)

Awhile back I installed an MIL Eliminator, but it never worked very long.

I just want SOMETHING(ANYTHING) to fix or get rid of my CEL. Any help or advice is appreciated.

Thanks in advance!

CN-Water bogged rear 02 sensor(I think) making my car run great temporarily. How can I get rid of P0136 CEL code?
