Hey Juan! Good diagnosing skills, sounds like you've got your bases covered. I feel like there's something going on there with the rich idle though. Have you had a chance to pull each injector and inspect the o-rings for leaks? You could also pull the rail with the injectors installed and prime the fuel system to see if it leaks. Or pull all your spark plugs, prime the system and listen/look for fuel mist coming out of the cylinder. Another symptom of this would be occasional hard starts and oil that smells a bit like fuel.
My car had a leaky fuel injector and I still saw somewhat normal AFRs and would start most of the time. Might be worth swapping them out with some known good ones. You should also change your oil if it turns out to be a leaky injector.
