AEM Wide Band Problem
Today mid way through my commute to work my cruising afr's went all the way to lean......Typically my crusing afr's bounce between 14.3 and 15.1. Under greater WOT percentages my AFR's richen up nicely to exactly where they should be and the sensor reflects this.
Why would cruising all of a sudden go straight lean? Is the sensor going bad? Im at a loss. Sensor has been in car for about 1 year now exactly all under E85 conditions.

When I blip the throttle and get into any kind of boost the sensor reads normally. The guage richens up as it should. It is just idle and cruise that pegs all the way lean now.

Seriously I have lost my mind. Bought a new sensor and come to find out the second bung on my downpipe had the plug back out. That is why it was reading lean. I didnt really notice the exhaust leak because currently I used the OEM gasket on my MAP O2 elim by accident and I am having a bit of dump at idle. I need a beer and a break. ha ha

i had this happen to me, but mine was an easy fix. the connector wasnt all the way in. if your saying its plugged all the way in check your pins and make sure there not bent. also check your o2 wires and make sure none melted on your exhaust. that would give you a false reading

Dumb me I went ahead and ordered a new sensor. When I got under the car to install the new sensor II discovered that the old one was still perfect. It had just backed out. Or, I'd forgot to reinstall it when I had done some exhaust work.
