O2 Sensor Problem? Code P1273

O2 Sensor Problem? Code P1273
So, I was aware for a while that my O2 sensors would eventually need replacing, after I discovered that some of the wires were corroded. The other day, I noticed that my 2005 Coupe felt a little rough. The SES light came on, and I pulled a code P1273.
Can anybody help diagnose whether or not this is indeed related to one or more O2 sensor(s)? Here are some reading I pulled:
Fuel Trim Bank 1 Long Term: 5.47%
Fuel Trim Bank 2 Long Term: 0.78%
Fuel Trim Bank 1 Short Term: -2.37%
Fuel Trim Bank 2 Short Term: -6.25%
Fuel Trim Bank 1 Sensor 1: -2.34%
Fuel Trim Bank 2 Sensor 1: -6.25%
O2 Volts Bank 1 Sensor 1: 0.27
O2 Volts Bank 1 Sensor 2: 0.28
O2 Volts Bank 2 Sensor 1: 0.60
O2 Volts Bank 2 Sensor 2: 0.28
These were pulled at idle. I will also note that the car was Osiris tuned a few years back. It seems like there might be a problem with the upstream sensor on Bank 2, right?
What are the risks of driving this for a few days before I can get it to a mechanic?
Thanks in advance!
EDIT: With more reading it seems like P1273 is actually Bank 1 lean, so I'm not sure what's going on.
