Default Master brake cylinder and Idle problem

Recently my master brake cylinder went bad (about 1 week ago). My engine would usually idle between 800 and 1k, now it will idle at 1500 - 2k sometimes. Any idea on what I ****'d up?

I would guess the vacuum line with the check valve from the IM to the brake booster...might have a leak there somewhere.

Take some brake clean and spray on the brake booster. See if the idle increases or if the engine all most dies. basicly your looking for your engine speed to change. It could be the hose, valve or the booster itself (not likely but possible).
