Welcome to the forums. Start by checking for vacuum leaks. Check your fuel pressure and ohm your injectors. Also check to see whether you have any codes present. Let us know what your results are.

OK, what is the pressure while the fuel pump is running? I once had a great fuel pattern, with 2 lbs of pressure. Had to keep feathering the throttle to keep it running. For 3 months I refused to check the actual pressure. Turned out I had a Hole in the rubber line between the pump and the pick up tube is why I ask. Again, it appeared to have great fuel pressure to me. Not many people have a TBI adapter to check fuel pressure, maybe you do. That's why we have to ask what the actual fuel pressure is to assist in determining the failed component.

Ohm your injectors...should read around 1.3. And check the spray patterns of your injectors as well...should be conical, not dripping.
