John, my Cavalier keeps the engine turning around 1100rpm when I NC. But the Scanguage reports idle fuel consumption rate, 0.4gph, regardless of rpm. As long as I'm burning fuel at idle rates, I'm not concerned what the rpm is.

I don't think interrupting the VSS will get your engine to idle. I think the ECU is sending idle-amounts of gas, and our engines are just getting a little extra push from the not-completely-decoupled slush boxes.
