Can you replace only one front o2 with a 11131or do you have to replace both

i bought the densos at advance to replace both front o2's in my hooker lt's /ory combo. i had heater and slow switching codes and hoped to cure both with new o2's. Its been 4 days and sofar the New DENSOs have passed the heater and slow switching, but now it tossed a running rich on both banks and im STILL waiting on EVAP and AIR monitors to complete.

Can i get some clarification on this tuning out the slow switching idea? do you need to Replace O2 with WIDEBAND?
