That is what I'll plan on doing tomorrow. I was thinking on this, if the idle is a little too low to begin with, it would stubble when trying to bring itself naturally to idle rpm right after going over would it ?
You might get the same results by just holding the brakes and giving the throttle a quick stab.
Or buy holding the brakes, give it a little throttle for a few seconds and let off quick.
I'd bet it does the same thing without the car even moving.
