code 41 and 91 help please

Reset the fuel trims after you changed the o2 sensors by disconnecting the battery for a little bit?

I don't think it matters except for warming up but you can check for power for the o2 sensor heater, should be 12v with the key on run....that orange wire going to the back of the motor is the ground for it.

If you got access to one I would hook it up to a piggyback w/ datalogging to check the o2 sensors for proper signals (rich lean rich lean)...or you can hook an analog voltmeter I believe to the o2 sensor signal wires (29 and 43) and look for the same thing..just so you know the computer is getting everything it should properly. Besides that im running out of ideas too.
