    Question Engine Blowing!?!

    Just wondering what this problem could be. When i give the car some throttle, just before it responds it makes a blowing noise, like a football pump, without a football on the end lol, just briefly until the engine responds. is this a vaccuum pipe leaking air or something ????

    thanks alot

    there will probably be a load of black soot around the bit thats blowing but youll need to get on your hands and knees. it could be the top bit of plastic that goes from the airbox to the throttle body, sometimes it leaks a bit there
