After being told that my cats are essentially doing their job and heating up to optimal temps to burn off exhaust correctly, and that my O2 sensors are effectively working and measuring what they are supposed to be measuring, I can't help but feel like the missing link is that the results O2 sensors are sending are not meeting standards of the parameters in ECU. I was told about an ECU flash, but nobody knows anything about it...I can't help but wonder if a different fuel burn might be enough to get back inside those parameters.
I'm doing fuel treatment, solely based on the mileage and service maintenance that it's ready for anyway, but at the same time, I'm running 93 through it for a bit to see if
(1) the issue will correct itself on its own or
(2) I can clear the code and it not resurface
In the mean time, I wanted to gauge whether or not there's a consistency of the issue showing up between those who only use premium vs those that don't.
