try raising the timing up a little bit without checking it, than disconnect the tps and it shouldnt stall out, your timing is probably really low.

you need adjust your base idle. check out se-r.net and look up idle adjustment. i had the same issue. here's my interpretation of how it works. your base idle is the "phyical position" of your idle, meaning, it's the physical setting associated with your idle. the tps, on the other hand, is an electronic adjustment to your idle. if the tps senses that the engines is idling too low or is about to stall out, the ecu makes the appropriate adjustments to keep the engine idling; thus having the tps off causes the car to stall IF the base idle is too low. so if you can imagine, your tps and ecu are constantly compensating for your low base idle. once you up your base idle, then the tps would not have to compensate for it. the base idle screw is a plastic-like screw on the passenger side of the engine. so if you're facing the front of the car, from spark plug #1, look about 4-6 inches towards the rear of the car and maybe an inch or two towards your left. the screw faces upwards. i believe counterclockwise is the direction for upping the base idle. once you have your idle set, then do your timing. btw, prep the car for setting the base idle the same way you did it for timing - rev at 2000rpm, three blips of the throttle, shut off, pull off tps, start car, and then you'll prob have to adjust idle immediately. good luck!
