Vacuum leak, that is the only answer. Something after the MAF is leaking.

First thing I would do is remove the breather and leave the catch can, that will see if the breather has a busted valve.

Okay I will try that tommorow and see how it works out, also would I have to plug in the thing were I have the two sides capped off one on the Intake and the other in the back of the engine?

Yes, that is how metered air goes through the crankcase and to the manifold. The breather allows unmetered air in, but is supposed to limit it to prevent codes. Yours might have a bad valve, might need cleaning.
