rough idle with break booster hose detached

I was using some seafoam this morning.. disconnected the break booster hose to suck up the seafoam through that hose and before I put any seafoam in the hose the car started to idle really rough. Is this the normal consequences of disconnecting the break booster hose?

Yes, completely normal.

Don't use the brake (get the spelling right) booster hose. Use a smaller one on the throttle body. you'll clean more of the intake manifold that way and it won't fubar the idle.

anytime you disconnect an intake manifold hose it will run funny because unmetered air is entering the engine....like Matt93SE said...use one closer to TB

seafoam....
