i have a 7 psi tial bov and when the car is on idle it opens up about half way causing a leak and the motor doesnt idle right. i put my brothers 11 psi spring bov on and it still opens up a little bit and the motor still doesnt idle right. but when i plug up the vac hose to the bov it idles perfect. my bov is on my cold pipe. do i need a higher spring? my boost guage reads at -20 to 22.
please help me.
thanks, brent
