Honda Civic bogging problem?

After I swapped my Intake manifold, my car starts to bug down on all gears.. And the idle is rough like it seemed to be having a hard time breathing that it want to kill itself.. I got the other manifold from the junkyard, so it might just be dirty? Or could it be sucking air or vacuum leak? I think I did everything right and I don't understand why it bugs down like that..

Any thoughts about this?
