I haven't opened it up to check hose fittings. The last time I had 0456 code one of the hoses was loose so easy enough. But all the misfire codes (for all cylinders) leads me to believe it's not the charcoal canister anymore...but what do I know...
The spark plugs are pretty new (2 years old max) so I'd hope it's not that. AOS seems like a likely culprit, but to your point I don't want to run the engine if I don't have to; probably just have it towed to my indie

If you had said there was no smoke I would be leaning towards a vacuum leak, but the smoke to me is either AOS or something more serious. I never got any engine lights when mine went even though it ran horribly. The quickest way to test it though is the oil cap removal. It could offer some peace of mind if it’s very difficult to remove it with the motor on
Keep me posted
