Well I was not surprised by the wonky fuel trim on the bank with the broken O2 heater but the strange thing that happened was during the course of 90 minutes drive the other bank joined right in and both were slammed max 12%
Today when I first started it ran pretty crapily which I expected. I cleared codes and drove to the auto parts store for injector cleaner and with only 1/4 tank it should do a good job.
Oddly when I checked the trims on the way back from parts store they were normal (last pic). I have a hard time guessing what could have been the cause unless like I said there is some deeper level fuel trim that took maybe five starts to clear.
I have noticed that changing a sensor often won't fix the heater dtc unless you force a reset by running with the O2 in question unplugged for 1-2 starts.
I'm hoping somebody else experienced similar where it took a couple days and half a dozen start cycles before it came back to proper operation else I still need to root out the actuak cause = fuel pump or FPR/filter.
