2003 Discovery 2

I had been getting a code for a Bank 1 Sensor 1 faulty O2 sensor for awhile (and ignoring it). Recently, the CEL began flashing and the exhaust started smelling extremely rich and the truck felt like it may be misfiring.
I immediately replaced all O2 sensors and plugs.
I skimped on the O2 sensors, and the front two were reading 0v, so I purchased Bosch and replaced the front. Nothing has changed and I am getting the following codes and live data readings:

P0150
P0305
P0304
P0306
P1300
P0300
P1171
P0171
P0332
P0130

O2 Sensors
1/1 0v and shrtft 0 (but it did jump up to 25 multiple times and back to 0)
1/2 .895v and shrtft 99.21%

2/1 0v and shrtft 0 (also jumped to 25 and back to 0)
2/2 .855v and shrtft 99.21

TPS 0%
MAF 7.91 g/s
spark advance 19 OBTDC

STFT B1 0%
LTFT B1 25%
STFT B2 0%
LTFT B2 25%

Ideas? Thanks!

 

Vacuum leak, check all vacuum lines. Brittle I'm sure.

Have I ever told you how much I dislike DII's?
