Replaced radiator, lots of CEL codes... Help :(
I have a 2003 Mach 1 with about 130k miles. I noticed I had coolant leaking and took it to a shop to see what needed to be replaced. Got quoted at $1200 to replace radiator, water pump, and reservoir. I bought the parts myself and did in the backyard everything is good to go. After bolting it all back up, bleeding coolant system, filling, etc, I'm getting the following codes:
P0174 - System too lean (Bank 2)
P1130 - Lack of upstream heated O2 sensor switch-Adaptive fuel limit (Bank 1)
P1131 - Lack of upstream heated O2 sensor switch- indicates lean (Bank 1)
P1150-Lack of upstream heated O2 sensor switch- Adaptive fuel limit (Bank 2)
P1151 - Lack of upstream heated O2 sensor switch-indicates lean (Bank 2)
P1152 - Lack of upstream heated O2 sensor switch- indicates rich (Bank 2)
I'm at a loss... It's worth mentioning that before replacing everything I was already throwing low voltage codes for Bank 1 and 2 sensor 1. Could I just need new O2 sensors? Is it safe to drive this way?
Also - I have Kook's long tube headers and high flow cats if that could make a difference as well. Borla catback after that.
Thanks for all and any help!

I was getting a lot of those same codes off and on for a while after I did the 4v swap and they appeared to be nuisance codes because everything seemed OK until it wasn't. I started to notice degraded drivability until it wasn't drivable at all. It never died but I had a complete loss of power. I changed the O2 sensors and now it's like driving a new car.
