Issues with New O2 Sensors

It's all good J, your advice in past threads has helped me out immeasurably. I figured it was just a misunderstanding. I do see where a lot of advice is ignored and can see where it would be frustrating.

Got it all back together and it seems to be working fine. The O2 graphs look like they should. Thanks to everyone for their advice.
A recap of what I did:
Replaced both front O2 sensors
Changed the fuse to the emissions stuff
Disconnected the battery while I changed the sensors
Did NOT use dielectric goop this time
Wiped out each connector with a dry Q-tip
Poured a can of Seafoam in and filled up the tank from a different gas station that is off the freeway.

O2 sensor problems...
Hi all
I'm having similar problems with new O2 sensors.
2000 Discovery, with 90,000 miles. I just replaced both upstream O2 sensors with Bosch (black box from Amazon with orange OEM connectors), and then after 15 miles or so I'm now getting the following codes:
P0130
P0150
P1129
P0174
P0171
P1174
P1171
I've checked the connectors and spayed them with contact cleaner, I don't believe they are dirty or getting oily. I can't find any vacuum leaks. Didn't see any wiring issues. Checked fuses and didn't see any bad ones (although I'm not sure which fuse is related to O2).
When I watch the O2 status on a code reader, it is changing, but not by much, seems to stay around .2 for both sensors?
Any ideas?

Bosch from Amazon
The sensors I bought are exact fit for the Discovery, the part number is the same as listed on Amazon and referenced through the forum. They were in Black Bosch boxes and came with a warranty. It sucks they crapped out a day after putting them in, but these sorts of things happen.
I doubt there is a corporate conspiracy at Autozone to sell defective or incorrect parts to everyone who doesn't drive a Ford or Chevy.
