I have a 92 c1500 5.7 tbi. The truck runs great but if you floor it from a dead stop in will almost die at 3 grand and then pick back up. Its a real smooth shut down. Feels like the fuel was just cut off or something. I have already replaced a fuel pump, fuel filter, new plugs, new dis cap and rotor. I don't know where to go from here. It seems to be a simple fix but i don't know. Any help you guys can offer will be of great help. Thanks!!
