I had the same issue three or four years ago, it’s evap system and secondary air system that won’t clear. There are no codes or pending codes, I can be tested with one test incomplete but not two. I have found multiple sets of drive cycle instructions, it’s hard to do ten minutes of 43 mph here, it’s either city driving or freeway, and ambient temps have been quite high lately. I’ll just keep driving, it’s got to get there sooner or later. It’s not all that bad, I could be driving a POS car. Oh, I caused this, I replaced the battery a couple weeks before I took it for emissions and never drove it after the battery swap.
