I have just fitted a bailey dump valve to my 95 wrx replacing the original recirculating type, all seems to work fine except, now my cars revs drop to between 500 and 200 when i ease off the accelerator and when I stop at lights etc. it sometimes stalls completely, other thing is sometimes it makes a hissing noise when I am accelerating.

Any Ideas???

ok refitted it made sure its all tight and sealed, doesnt hiss now, but still idles like a bag of sh*te.

I think I may just take it off and put the original one back on

Youve probably bought the wrong one,you need Dv26"evo" for a scooby not the Dv24.

Btw been running a "evo" on mine for 6 months with no probs.

 

dump to atmos reknowned for idle probs. I got Blitz that came with car. Idles like crap most of the time.

 

Dont accept poor idling!!!!
Means valve is not closing, means wrong valve/internals need cleaning or **** product IMHO of course
As stated, you most likely have been supplied with the wrong valve, our cars need one that shuts on idle unlike R5 turbo's (for example) that stay open on idle..

sounds like the spring is to week, thats if it has a sping, not familer with that type.
on mine its adjustable by putting packers in, therfore more presure on the spring and i got a better idle
hope this is some help
