1999 suburban 5.7 vortex misfire/sputtering problem

[Bigtimemike]

My 1999 Chevy suburban started to sputter like a misfire. I changed plugs, wires, fuel filter, still sputtered. Went ahead and changed crankshaft sensor, distributor, cap & rotor and still sputtering. I just spent another 800 on replacing the fuel injectors with the upgraded kit and still sputtering. Can someone relate to my symptoms and help me out. I don't know what else to do. You can text me also if that's easier. 845-642-5460 mike.

do you have a check engine light on and if so what are the codes? have you done a fuel pressure test?
