hi all ive got a 98 turbo its got a baileys dump valve which is coming off next week problem is after ive stopped the car go back to start it its fine then when i set off just hear a whoooshing noise and the car splutters along then about 3000 to 4000 revs it clears and its fine any ideas wot it could be thanks

 

sounds like an airleak on one of the boost hoses just check them for splits and loose connection joints or you dump valve diafram could be knackered worth a look ?
