cheers for replys, ill give it all a clean later, but refering to the vacuum leak, under reasonably hard accelerating, mainly in 2nd and 3rd, i do get an air noise, only way i can describe it is *it sounds similar to my mates 9-3 aero turbo!!* or like a high pitch hissing of air??? never driven one of these cars before or even heard the engine sound so thought it might have been the noise of the cold air intake?? does that sound normal or sound like an air leak?
