Sounds like you removed your rear O2's, so you can disregard any codes referencing 'Sensor 2'. You can see a list and description of all the codes here. It is not uncommon to experience P1133/P1153 particularly after a header install. Search is your friend. Lots of suggestions. Could be your sensors, you could try some Bosch 13111's or some vette rear O2 sensors. There are some tuning settings that can also be made. Some of the other codes also show up after a header install. You should read this thread.
