FZJ80 Failed CO Emissions and Code 25

[IoN6]

I have a TOYOOBDI you can borrow to see the AFR and other values while driving around. Still crude, but better than codes alone.

How does it run >3000 RPM?

It runs great other than it failing emissions and having a low idle which is why this is so confusing to me

Replaced the other o2 sensor with another 95+ as I didn’t want to spend $200 on one sensor but I think I have to buy the oem ones as this made it the worse emissions test yet


Purple is the one from this morning it also had the cel pop back up. Haven’t checked it but I assume it’s the same code 25

Okay just checked the code. It’s now a code 26 (Continuous Rich) any thoughts? Or is it still probably just an oem o2 sensor will fix?

Wonder if you have an injector issue. Any idea when they were last cleaned or replaced?
