Correct. It had no error codes when we purchased it and ran fine for a year until this recent event when it lit them all up became a smoke cloud generator.
No overheating, no oil consumption (granted.. it could be burning oil during the smoke cloud, but he/we learned not to go WOT until it's fixed, so it runs relatively normal if you only drive moderately).
I suspect if I replace these two downstream O2 sensors and drive moderately it'll be error code free and drive fine.. until we go WOT and then poof.
