I added STP or similar injector cleaner to fuel tank. 1/2 bottle per 1/2
tank then remainder in a full tank. The stuff smelled mostly like diesel
fuel if I recall.
No run issue prior, figured it was good maintenance to run injector cleaner
through.  Check engine light coming on recently while driving was something
that used to happen but that was due to a missing "sensor ground" ECU 33 if
I recall. (yes)

I connected that missing ground over a year ago, which solved that issue,
so was surprised to see the MIL come on while driving. Wondered if any WBX
users
had run into an O2 fouling situation after using injector cleaner in fuel
tank

When light came on this time, it threw a 2324 DTC for O2 system:
