With the pedal slightly pressed it probably wouldn't have gone much over 2000rpm. I can hold mine anywhere from 1600-3000rpm with various pedal positions without it running away....

PawoSD, All i could think of in that short amount of time was "run-away" which is why i took such quick action. Usually I cant hear the engine running with the storm door shut but when I heard it over the TV, I knew something was a lil different. Thanks for the insight, it kind of reminds me how holding the pedal at a constant position within the boost range allows the engine to eventually take off. Its not something I expected but now i know what to look out for.
