i would now be checking the pcv and hose, unplug the isc..
i doubt it would be the tps, the tps alone wont make it rev that high. the tps sensor will tell the ecu the throttle is open, but without the air flow it wont rev.. so that tells me there is air entering the manifold from somewhere... |

the butterfly is as closed as it gets metal to metal
i was wondering if its possible for the ISC to get stuck open actually but thought it was a stupid idea instead of putting my finger on the line ill swap it with a working isc i have my hand almost fully covers the hole almost and ya my hands are small im a really skinny little fella and my hands can collapse in on them selves (part of being double jointed i think never found another person that can do it) i think they were collapsing in on themselves but i didn't concentrate on that

Ever thought about using an old fashioned vacuum gauge?An engine in good condition at sea level should read between 18 - 21 inches of mercury on the scale.Any deviation will tell you a specific problem.
