I was being sarcastic.
Of course I'm in favor of getting as close to zero emissions as possible but instead of the EPA and the RTA being finicky about fault codes that might have no effect on emissions at all, they could invest in a better public transport system so people won't have to use their cars as much for their normal daily activities.

Yeah, it's likely that some sensors are not reading ready, that may be due to bot going through the proper "drive cycle", or it may be that the tune has sensors turned off. You should be able to get a tune from Bama (american muscle) for emissions that has all the sensors turned on.

Fun stuff... If you're running the aftermarket CAI is it CARB certified? CA is very finicky on that. If you recently cleared codes or unhooked the battery, you have to run what called an OBDII drive cycle.
MOST STATES have emissions laws in place to avoid people simply trying to erase CEL codes or hide faulty sensors by disconnecting the battery. Every sensor has certain amount or number of conditions it has to go through for it to be cleared on a Code scanner. Most if not all are cleared within a few days of regular driving but you can clear them completely in a day if you follow the instructions.

I had bad race fuel one time and it took three complete fill ups to go away.

Ok, so I hear all that and I appreciate the feedback. This car, keep in mind, has sat still for most of the last 14 months. I understand that the 89 octane that I ran in July 2015 may have developed a bit and could be throwing off the exhaust numbers. Can I just run the 89 until it's low and then fill 87 on top of it and go through the above steps??--- or do I really need to drain this thing via tank drop or fuel line drain?

it's perfectly logical. P1000 is an "invisible" code (won't put on the check engine light) which sets until the car has been driven enough for the OBD monitors to reach a "ready for test" state. If that code is present, they'll find it on the initial scan and fail you right away before they put the car on the sniffer because they assume you're trying to hide something.
and I wouldn't call them the "smog gestapo," since this is what Los Angeles used to look like (in 1980):

I tend to agree with siber express. It's all about the money like everything else in this country. They are a business nothing else. A properly maintained car can and will pass a sniffer without cats. Seen it done multiple times but will fail based in visual. Cats are there for people that neglect their cars maintenance to deal with the excess caused by bad plugs or a myriad of other maintenance issues. So since some people are neglectful we all get penalized. Ok rant over back to the original issue. Is your battery fully charged now? A low/dead battery can cause all sorts of issues. The PCM needs a certain voltage to run properly and perform its checks. I've seen a weak battery cause a p1000 that won't go away more than once. Check your voltages to be sure they are in spec. Also most performance or race tunes have the rear O2s turned off so it will never show ready now matter how far you drive it. If you have a scan tool it will tell you which monitors aren't going ready.

FWIW as an engineer (now retired), I believe more in the concept of getting emissions as close as reasonably practical to zero. By definition, that isn't and probably cannot ever be exactly zero. It's a somewhat less stringent philosophy than the one that I worked under while in the power industry ("as low as reasonably achievable"), but we're dealing with $$$$$.¢¢ cars that have to sell in large numbers here, not a handful of multi-billion-$ power plants.
Even with emissions, there exists a point of diminishing returns.

Oh I agree but they give a fairly lenient range of emissions levels that the car can be in between and be considered compliant. My point was even without cats a maintained car can get the levels within that range without too much fuss. Even under load.

Exactly there's definitely a point where the cost of cleaning up the exhaust any further is just not practical. But after doing my own research I think it's a joke that the general consumer is caught up in states like California that really do go overboard. I'm all for a clean environment but the cars on the road have a minimal impact on the environment. It's almost like they are beating a dead horse at this point. They would have a much higher return going after some of these older dirty plants that real awe many times more pollutants than our vehicles. But they won't because big business gives too many kick backs to those in power.
