stalling/sputtering.....again

just wondering if anyone one had any ideas.,my 98 z24 is stalling when i start it,everytime i start it.it starts,runs for a few seconds and then stumbles down and misses for a few seconds and then it stalls. if i try to rev it up to stop it from stalling it misses really bad and some times pops back through the throttle body. it only does this when i start it,other than that it seems to run fine,other than having a small amount of hesitation at lower engine speeds (1000-2600 rpm).it does it when the engine is cold or warm.any help would be appreciated,thanx

TPS, maybe?

Fuel filter... coil packs.... IAC???
