91 sonota shounds like a popcorn machine

When started car runs ok...but after a few minutes it starts to spit and sputter and kinda sounds like a popcorn machine. Has new wires, plugs, coil, exhaust, converter, pcv valve...the whole nine yards. New injectors too. We you step on it you get a puff of blue smoke then the miss. Then you will hear it rev itself a bit.....Any ideas?

You should probably check your fuel pressure. When a fuel pump wears, it often works well enough when cold, but as it warms up it tends to lose its ability to deliver fuel, especially when the throttle is applied.
