O2 sensor help.
I have a 2004 5.3 swapped into an 01 Mustang,when the O2 sensors are plugged in it runs horrible. I put new Bosch O2 sensors in and it didn't clear up. I checked my wiring at the sensors and it's good(ground,12V,and sensor ref.).I did have a p0155 code but so far it didn't come back. Is there some kind of relearn for the ECU and O2 sensors?
It runs really well when they are unplugged, any help??

Which bank is which? I was unaware that it mattered since I'm only running the fronts. I traced the wiring back to the ECU to make sure that I have bank 1 sensor 1 and bank 2 sensor 1 and I do. Both sensors are located before the cats.

Ya, I know they are used for fueling. I am running in open loop right now because I can't figure out what the problem is.
