Bought Reader, have codes....

02 4.6 V8 Screw with 97,000

Bought an Actron Code Reader and came up with the folowing 2 error codes:
P0171 - System too Lean (Bank 1)
&
P0174 - System too Lean (Bank 2)

So...I'm clueless as to what that means. Anybody point me in the right direction of next step to resolve?

Thanks!

If I were a gambling man, I'd lay odds that your PCV elbow is leaking.

That would be a safe bet.... About 80% probability!
