Service Engine light wont go away - Bank 1 & 2 too lean?

Help!! My engine began running rough and the service engine light has been on. I have cleaned my Mass Air Flow sensor, been throught a dozen bottles of injector cleaner, and I just replaced the two upstream oxygen sonsors. The engine still idles rough and the OBD code shows Bank 1 sytem too lean, Bank 2 system too lean, as well as a slew of random misfire codes. What the hell!!! What should I do next? Any suggestions
Thanks
