Hey,

So I've been experiencing some really weird WBO2 fluctuations where I am just driving around holding the same load or even just standing and idling on the street when suddenly my wideband starts to act up and go super rich 9.6:1 and then stay there for some time, before it goes back to stoich sometimes it even happens on overrun, let of throttle, and the wideband peggs at 9.6.
I thought it is just a faulty sensor so I replaced with a brand new Bosch one, and after 2 weeks the issue is back, however my tune did not change at all, and otherwise the car feels and drives fine, no issues what so ever. When the wideband reads 9.6 at idle the car just idles perfectly fine. Luckily today I was managed to log the whole thing because it's so random, it's impossible to reproduce it. Now I just would like to figure out if my Zeitronix module is just going bad or I my car just eats WBO2 sensors every freakin month. Please guys have a look at the attached file in case you can spot something that I did not.
My WBO2 is wired into the secondary O2 ECU pin, and available in the attached log as uushk2_w.

Thanks in advance!
