STARTS IDLES FINE BUT WHEN STEP ON GAS SPITS AND SPUTTERS THEN DIES

1990 Cadillac Seville • 120,000 miles

When I first start it up the engine races then slows for a miniute or two then it smooths out but when I step on the gas it either stalls or misses then sometimes it backfires and quits. Could it be the tps, map, or the iac. If not what else could it be.

Check the IACV, MAP and TPS sensors to include a fuel pressure check
