Hello!
I was with a fake air intake in my car
My Wideband started to shoe that the car was totally poor (1.23 in lambda)
I stopped the car in the garage and solved the problem of leakage of air, it was a connection on my FMIC...
I solved the problem, however, the probe remains strange.
so I turn the car on, it works perfectly for about 20 seconds and then Wide shows 1,231 straight.
if I turn it off and on, it works perfectly again for a few seconds, but then it returns to the same fault.

I test the wide voltage and did several tests, the best I got was to let it oscillate between the correct marking and the mark 100% poor.

I'll try to attach some videos.

Anyone have any suggestions for what might be causing this?

P.s - Sorry for my bad english and video language. Im from Brazil.
