Is your throttle bypass valve set correctly?
Unplug the bypass valve then set your idle with the throttlebody set screw, and plug the bypass back in (having trouble with the actual name, IAC or whatever you call it). Once you've set your idle then set the TPS.
Is the ignition timing correct? try fiddling with the distributor to see if you can get it to idle, if you can then set the timing and go for the idle adjustment.
