Your oil temp is fine...mine ran 220-230 a lot & wouldn’t pull timing & derate unless it got past 240-250

Yeah I wish I lived near some of the reputable Z shops lol. Guess Ill have to dig around a lot here in rural NE Ohio for someone knowledgeable in VQ to look at it.

Is there anything common that could just kill a new AF sensor? Bad luck obviously lol.

Wonder if there is any other issue thats the main culprit that kills upstream sensor?

Other then that I guess I could just attempt the CJ return or buy a Brand new basket... both are the same price baically, assuming my sensors are still good then fuel is the last thing i can think of...

And yea its not going back to nissan, i gave them their 1 shot at diagnosing it.
