why cant i pull off the tube from my stock bov to the intake ,every time i atemp this the car idles funny, ive also blocked off the same tube so that it doesnt loose vacume ,so when i rev it up high when the revs come down it stalls im guesing that it has somthing to do with the mas air ,but what ? and how do i get the bov noise ,and the car to still run good and no rough idle?????
