Not too long ago my 97 Town Car developed what I believe to be a vacuum leak. There is quite an audible hiss like suction, when idling but you have to be standing right next to the hood to hear, or pop the hood and you can really hear it. Seems to be coming from right around the IAC on the throttle body. Changed it with new gasket and no change. Is it possible to have a crack in my intake manifold right by the throttle body, Since it has gotten worse since I started hitting the n2o at the track. Wondered if that was possible or if anyone has ever had a vacuum leak on a tc and knows where to look for vacuum lines. Thanks
