hey can a bosch valve also delay throttle response and make the car feel sluggish when trying to accelerate? and when its old does it sound like air is coming out or something? because i checked spark plugs which are good , and also fuel pump just been replaced.

If the diaphram splits it can "hoot" like blowing accross the top of an empty bottle, other than that they just work........

Have you cleaned the throttle body?

Did you look at or change the plugs? How old are they?

Stop worrying about everything else that could be causing the car to feel like that for now. just get the plugs changed, and if that doesn't work- then you can start worrying :cheesy:

Nice post :p

Actually very good advice too, start with the basiscs, the cheap bits ;)

quick question, my valve does hoot, only at a certain rpm and throttle position, then it goes away. Diaphragm split?

Yep, and its leaking boost when it hoots :confused:
