So I've recently been having this problem with every time I start my car, the first time I do a WOT pull, or, if its colder and I apply throttle, the car will run rich, pegged at 10.0:1 on the wideband and the car stutters with lots of whiteish smoke coming from behind me. Anything after that, the car runs perfectly fine. It's just the first time the car gets a decent amount of throttle, it does this.

I also believe that my new ISC is blown, which I could only think to be caused by my FIAV leaking. Could the FIAV be leaking, breaking the ISC, then under throttle, the engine ingests the water causing the rich condition?
