What did you do to your TJ today?

Drove around checking open/closed loop monitoring O2’s.

Had fun, everything worked. Until it didn’t
Worked —> heat soked for about 15min while i was at the store—> open loop due to system failure

Drover around for 15 min until it jumped back into closed loop —> stayed there for a few min —> fuel system unknown. —> drove home, wiggled o2 plug ( upper) —> went back to closed loop, stayed that way for another 25min of idling while i checked grounds with multimeter 🫣

Waiting for GPT to go over the entire 55min video and ordered a NGK set while im waiting.

Good rabbit hole times ( o2 load jumpe between 0.08-0.9 the entire idling time)
