2001 Chevy S-10 pick-up Extreme (6 cyl), OBD reset for engine light, drove 300 miles & caytalitc & air systems still show "not ready" for testing. Need maximum of one system not ready to clear emissions. How/when will these systems reset?

That just means that your driving has not duplicated every situation that the computer is looking for. There are 6 different monitors that have to be cleared and they each look at different things.
