that's the right direction. though, it sounds to me like somebody set the idle real high to keep it running (i.e. cover up some other problem). with it set too high, it would have the same effect as trying to start the car with your foot on the gas (too much air). find the idle adjustment screw and back it out 7-8 turns. see if that helps. if not start it with the fluid again and see where it idles. keep backing the screw out until you get to ~1000rpms.
throttle position sensor could be bad or installed wrong (or not connected).
also a Idle Air Control valve (IAC) that is stuck (internals not moving properly) could prevent the car from starting. this generally can be fixed by taking the internal parts out, smoothing them out with sandpaper, doing the same to the bore, and adding some lubricant to the spring and everything else.
very likely, your problem is with one of these three items.
any check engine light on, while it's running?
if so, reset it by unplugging the batter for 10mins, then see if the light comes back.
