Default P0174 System Too Lean bank-2???

2001 Ranger 3.0 V6 Flex Fuel 2-wheel drive 112K

CEL came on and got the code "P0174 System Too Lean bank-2". I need to fix this asap so I can pass emmisions (Assuming I will fail). I just bought the truck 3 days ago and the light came on the next day!! Go figure. Whats bank-2? Thanks for reading this!

I am experienceing the same problem. I am led to think its a vaccum leak. every one says to check the elbow at the pvc valve, and all hoses. I am going to plug the brake booster and see if its leaking. From past experience i am guessing its the intake gasket and injector o-rings.
