Aem wideband reading lean
So i installed my Aem afr about a month ago and noticed some wacky readings, all over the place… running lean etc. I found a couple exhaust leaks which i addressed but it still did the same thing! eventually i sent the gauge and sensor back to aem, they checked them out and said the sensor was good but the gauges chip was messed up so they replaced it. i put it back in my car but same…old..thing. The car starts up normally with basic readings, but then it starts reading richer and richer until around 12 and then it goes full lean and stays like that. sometimes around normal driving ill see some numbers but under full boost it always shows lean. BTW my car only has a full turbo back, that is it. Help me evom community, you're my only hope.

I just changed to a butt connector cause my t-tap for my power wasn't really working. It's better now but the only thing is that under boost it still shows dashes

So I have a theory. When the exhaust/ sensor is cold in startup itll read okay. But after driving it on the street of under boost it doesn't read. So maybe when the sensor is hot it won't read? So maybe it is the sensor
