-28% on the STFT and +26% on the LTFT. Could it still be the o2 sensor on bank 1 or is it a software problem.

My SES light came on and my car started idling rough. It is giving me a P1415 code which says it is a secondary air system in bank one. My car does not have a secondary air system. I checked for leaks in the manifold, sprayed some carb cleaner around the intake manifold to see if there was a intake leak, no change. I disconnected each coil pack while it was running and the car ran worse, I changed the plugs and still get a rough idle when stopped at a light. My o2 sensors seem to be putting out around the same voltage, the fuel trim numbers are higher than normal,
