stumbling, stuttering, and not going anywhere

my 87 t11 is stumbling really bad while cruisin, i have changed the injectors, regrounded the wires to my ecu, changed my fuel filter, read all the threads. at least once a week i turn it on and drive, press the gas pedal and it goes nowhere just back fires and sucks in air, until it gets past 4k rpm but i have to let it sit for like 5 mins then its fine. MY injectors were 550cc/720cc, i changed it back to stock and i have an r-tek 1.7 could it be that or maybe my fuel pressure regulator
