My 95 3.0L showed the same codes. one of my fuel injectors was dirty. so it was getting clogged and not producing enough fuel so the 02 sensors showed to lean. i put a new injector in and it was fixed. ti check which one it was i just found which cylinder was missing. while its running individually pull a wire off of a plug and if the truck runs more rough then that cylinder is running. when you come across one that it doesnt change when you pull a wire then you know that that cylinder is not firing. make sure your plugs are correctly gapped and that your wires are good. most likely your injector.
