Ok i have a bad vacuum leak coming from the brake booster but from the inside. I hear this loud hissing sound and when i step on the brake real hard it goes away and the car stalls. what is this and is there a easy fix? and one other thing since i put the intake on i have a small popping sound coming from the intake inlet when i romp on the throttlebut it will do it every so often and i know the timing is right can it be caused by the different nipple i put on the injector? the nipples are all the same but "one" and can that cause the car to sound and act like it is runniong on 7 cyl untill a cirtain rpm then itsounds fine after like 3000 rpm.....
