Smog issue
I keep taking it to the smog shop to get it done and they keep telling me the
Heated o2
Evap
Sec air pump
These 3 keep saying they're not ready to be tested.
I've driven 80 miles since resetting the check engine light.
All help is welcome.
Thanks in advance

Others can help you with more specific information, I'm sure.
But here (link below) is information on GM obd drive cycle you can look at.

Never followed the above instructions, but when I used to inspect vehicles, I would drive down the access road or highway @ 55mph for about 25-30 miles total and would have about 95% success rate with less than 2 monitors reading "Not Ready" which was enough to complete an inspection.
Also had a guy drive to dallas and back with no luck. His issue I believe was from his tune.

Some states allow up to 2 I/M monitors to show NOT READY and still pass. Resetting ANY CODE(S) will RESET ALL the I/M monitors-FYI. Get a cheap Actron scanner and you'll KNOW before you take it in how many I/M's you have in the "OK" state. You can't see I/M status via the DIC.
