I doubt it is the IAC. For one the dealer replaced the IAC about 6 months ago under warranty...(which is now expired). Also, my car runs perfect after I get it started. So I suspect the IAC is ok.
Also, as far as I understood, putting the pedal on the floor cuts the fuel pump...to avoid flooding the car. I might be mistaken on this..in fact, I am not sure if you can flood an SVT...
I checked the voltage across the battery...12.8V, so I know that isn't the problem. I ordered new plug wires, but I don't think that is the problem.
I think it might be fuel related. Is there a fuel pressure check valve? Or could it be the fuel pressure regulator, or pump?
Thanks,
