Well last night i went ahead and was looking around the engine bay, and disconnected this thicker looking line that goes into this circle black thing that has a valve that "Opens and closes" when you hit the gas.. I dont know what it is but when i disconnected that it boosted at 100% and i got all my power back, but when i reconnected it , i would go right back down to 50%. It has to spots that look like you would have two lines going into it, but there is only one line connecting to it =/ i dontk now what it is, and i dont have my Haynes Man, to actually look and see so hopfully somone here can tell me what it is...

I checked that line and it seemed like it was fine at the location, pushed all the way up to it , and there didn't seem like it was leaking, the car just seems like it's starving itself and im really unsure as to what that could be, cus it does it at startup and most the time if i put it in gear it will shut right down, and you can hear a giant vac leak, then after i let it warm up half the time it just doesn't want to run that long at all, and like i keep saying it keeps getting worse. Im bringing it in on Tuesday but would much rather save myself the money and figure this out myslf =/.
