F cam sounds like stock cam ?

I have the same problem with the camshaft in my engine. I have the b cam and it does also sound like a stocker. I am going to try the IAC event that you tried and see what the effects are with mine. I know the Bcam shouldnt sound stock, but the sound file of the blue car idling is kind of surprising. Ford Racing has a plate to install inbetween the sensor and the TB, i belive it is adjustable, so you can have rich or lean idles. I am gonna try to find out some more information about this problem today.

Tried the IAC event. Nothing changed. This has to be the "wrong cam". The whole point of the idle air control valve is to compensate idles. So the cam you installed cannot be right. If thousands of mustangs have a nice loping F-303 cam and yous doesnt than I guess it cannot be an F-303. My cam is supposedly a B303, but I bet ya it isnt.
