Why would a 2001 Ford Ranger 4.0 V6 have lean fuel bank 1 and bank 2 and multiple misfires?

If you're only getting a lean indicator and no other problems you might have a vacuum leak or possibly a problem with the EGR valve. The multiple misfires (assuming P0300 or specific cylinders, P0301 ~ P0306) sound like lack of fuel to the injectors causing misfires, also resulting in O2 sensors "sensing" lean mixtures as a result.
