Default Supercharged C5 with lots of SES codes..

A friend of mine has an 03 C5 auto bone stock with a P1SC blower on it.. It ran great all summer with no codes whatsoever. Now 1 week ago it threw a bunch of codes and now the idle surges and so does cruising..
I checked it with my Predator and got these codes..

P0157- o2 sensor bank2, sensor 2 low voltage
P0171- Bank 1 fuel system too lean
P0174- Bank 2 fuel system too lean
P0300- Random misfire code

Now this car is bone stock except for the blower. I have been doing some research and it seems that if the rear o2 wires are corroded that would cause all of this.. I am not sure what to do about this.
The car was dyno tuned when we put everything together.

Could it be that the sensor got wet and failed causing this??

Thanks for the help...

You are probably on the right track checking bad electrical connections, but just in case, check the fuel pressure as well.
