Weird Noise. Help?
Okay, so I just started hearing this weird noise coming from my 04 wrx (vf34 and supporting mods) it's a short blow off valve sound that i hear once in awhile, but the thing that bothers me is that when i hear the sound, i can feel my car jerk back. I dont know what this can be. so if you have any idea, your help is greatly appreciated.

then my car would want to stall everytime i stop... i dont think so ... maybe there's a puncture along the vaccume line somewhere. I'll check ... but in the mean time, anymore suggestions?

Hmm, I think my car exhibits the same exact problem as yours. I did a quick inspection of my vacuum lines and didn't notice any obvious leaks, though they were somewhat brittle.
Does it sound like a high pitched and brief whistle (at least compared to the stock BOV)?
Also, do you also hear that sound when you're at idle and/or when you blip the throttle a few times while stationary?
I notice the jerk as well (only when the car is moving, of course), and its pretty annoying. I didn't notice this before I got a Borla Hush Catback installed.

i have borla hush also. but i dont think that's the problem. I havn't tried while im stationary. so iono. Im leaning towards mike's conclusion that the stock bov is leaking. .. since i sometimes boost creep to 20 psi ... my stock bov might not be able to handle it ... so im just gonna get a ssqv and then see how it is.
