I went to the store right down the road from where i live and on the way back it started hesitating and surging (driving through the rain)
I pulled two codes...P0132 High voltage O2 bank 1, sensor 1 and P0300 Random misfire detected. I cleared the codes and I'm about to go drive again to see how it feels.
There was another time a few months back when i went over a puddle after it flooded and my car did the same thing but that was before i had it tuned.
Car has been tuned for maybe a month now (i think) If i replace the O2's should that also fix the random misfire or is it something else??

Thanks.

Quite possible the O2 sensor swap will fix that. I had the exact same issue after getting off into some high water by accident. O2s got wet and after a few days, the SES started blinking at me cuz of misfires (car was running like ****, too). Swapped for new sensors and problem solved.
