vacuum leak on the intake manifold most likely, unmetered air is getting in.

well see the car starts fine and after about 4 secs or so it starts to blubber and sounds like its missing i was just under the car and one of the O2s is broke and not hooked up and its on the bank 1 side and the other O2 on the same side is black as hell idk if that would cause that and as im driving the car it misses really bad but after im driving for a while it starts to act a lil better but once i lay into the gas after about 4500 rpms it looses power and i let off and the car goes crazy and jumps and jerks and stuff and once i stop it idels at like 600 rpms and acts like it wants to die

fix the O2 but running better after it gets warm is a classic intake manifold vacuum leak symptom.
