I thank you kind sir for the info.
I’m going to double check the sensors tolerences before I replace it outright. Not too concerned about rushing to get it fixed. Car is still running great, and fuel mileage is not being affected to a point where I should get my panties in a tizzy.
I’m going to wait for a nice sunny, warm day, lol.
I’m glad it’s post-cat too, as I had that pipe replaced last fall, so it shouldn’t be as difficult to remove the sensor as it would’ve been the front, which is original from '96.
