Bank 1 and Bank 2 too lean?

I have a 2004 ford taurus. About a month ago the CEL came on, ran to advanced auto to get a code and they said my bank 2 was too lean. Yesterday, got a code run again and they said bank 1 and 2 too lean. They said it was probably my oxygen sensors. The car has developed a rough idle when first starting up and has lost some power and acceleration. I plan to take it to a mechanic soon, but until then i'm trying to find out what the problem is. Any suggestions?
