What causes the P0300 P0302 P0303 and P0304 on-board diagnostic codes for a 1997 Toyota Camry?
Engine misfires. P0300 corresponds to misfires that are random among all cylinders, whereas P0301-P0306 correspond to specific cylinders. I'm not an expert, but other posts I have read seem to suggest that because you are getting misfires across more than one cylinder, it's probably something like your ignition coil, distributor, etc. !

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.
