Chevrolet Camaro 1967-2002 - my 2000 SS has some problems 'help'

i just put my long tube headers and didnt hook up my o2's yet waitn to get longer o2's but its miss fireing and pops really loud when i rev it up to 2000 and let off. is it my plugs?

front o2's or rear o2's arnt plugged in?

I think you have to have the front or precat o2 sensors plugged in. I may be wrong.

that is your problem... you need the front two in and the rears people usually get tuned out or you can pick up some SIMS
