It should nit set those DTC's if the rear O2's were deleted and yes, they're setting because the cats are gone. As far as the lean code, it's kinda rare for one side only to set so look at anything on that bank that could cause a lean condition.
Look for anything on that side of the engine (bank) that can cause a lean condition. If the rear sensors were deleted in the tune, those DTC's would not set. If you can, look at BOTH banks' long term fuel trim and see if the other side is also on the verge of setting a lean code P0174.
You'd need a scanner.
non of this could be caused by the fact that some of your spark plugs are new and some are wet, rusted, and FUBAR?
