1994 Chevrolet Camaro running

When I try to crank it in the morning it won't crank I'll have to roll start it but after I do that it will crank and run all day just fine but no it won't hardly rev and if I put it to the floor it will bog and backfire and black smoke will come out of the exhaust this is my everyday car and she has been good until now and I do keep it well tuned up
