Problems at partial throttle

[The G-Man]

crazy you didnt get a code for that. but cel criteria is super low on OBD1 cars. im running into the same issue with my dad's 92 lexus. the o2 is dead yet i get a code for Air fuel mixture lean and not an o2 sensor code.

Yeah, I feel like it is kinda wasting the point of the check engine light. For the normal person and random mechanic, it would take them forever to figure that shit out.

Found this thread searching for results similar to my issues. So the o2 sensor on the F22 will work for the H22 as well? Not sure so I'm asking. If I had hair I'd have pulled it all out by now. Also, which pins am I checking for the resistance test on the resistor box?

a good denso or ntk unit will work with both motors. the ecu isnt that picky.

resistor box: one lead on black wire and other checking each of the red wires.
