no O2 sensors

[MGS88]

good evening/morning

I found my 2000 LC100 have no O2 sensors and they just put some nuts in the hole
yes I have very bad smell spreading like hell .its like burning something with gas> oil maybe? but it's not decreasing as I checked out


beside that problem, is it very bad running engine without O2 for like 12 years that usually comes with?
I mean do i have to replace the catalyst? trying to add O2?

Who knows what else is modified if the PO removed the O2 sensor! Good Luck! You should post some pictures of what they did?

Many non-US vehicles don't run any O2 sensors. Open loop system, I guess. Probably not as efficient but I don't think that is of paramount importance for them.
