Default Confused on code P1129 and some others after all new o2 sensors

I just replaced all 4 o2 sensors and keep getting these codes:

P1129
P0154
P0135
P0155
P0300
P0304
P0130

I checked cyl 4 for issues but all seems fine and not sure what P1129 means? Any help would be greatly appreciated.

I am just telling you what my book shows. Check and make sure you didn't cross the wires when installing the 2 fronts.

Here is another reference to the 1129 code, http://www.permoveo.ltd.uk/tabid/122...r/Default.aspx

Got it. Checked all connections but no noticeable problems. Read up on the 1129 code and it states errors can be no reply from 02 so wonder if 1129 is related to no activity code 0154
