97 camaro, issues starting, need help

ok, so i am confused here, i have a 97 camaro z28 . 10k miles on motor. it has 3 codes coming up. 02 sensor, secondary air injection malfuntion, and random misfire. So it turns over fine. it takes a few times cranking and it finally starts. not a few cranks, like crank, let up, crank almost starts, crank and starts with gas pedal a bit. ? so air injection? wat can be going on. i need help?

call me crazy, but I think of you take care of the issues that are throwing the codes, the car will start and run like normal.

i kinda have the same problem with my 94 f-bird it takes a couple cranks then bam fires right up but the first couple cranks i get nothing the only similiar code i have coming up is the 02 sensor which i dont think is the problem so i also would like too know :)

fauled plugs??
