O2 sensor and code help please
I just recently moved and have to pass a new emissions test and my check engine light is on. I took it to autozone and the following codes were diagnosed, P0116, P1408, P0150, P0154, P0401, P0156, P0158 and P0136. I have a 1997 A4 2.8. I was going to replace the coolant temp sensor as well as whatever O2 sensors were bad. Does this sound correct? If so, how can i determine if an O2 sensor is bad? Any help would be appreciated. Thanks.

Those codes are far too generic to be useful. You need to have someone with a VAG-COM scan the car and see what specific codes come up for your issues.
Personally I'd clear them out, drive, see which ones return.
