i has a problem. my wideband shows 10.0 all the time. during idle, WOT and also out of the exhaust....is this a indication of a bad gauge?

 

maybe the sensor is messed up. u got a local with one that u can swap guages real quick?

 

I have kind of the same problem, except mine is just laggy as hell. 14.9 afr while cruising, I don't think so. Pretty sure it's the o2.

 

Or maybe you have a issue with your car, look at the stock narrow band mili volts to see wut it says. Also check your connection on gauge and verify its all good before you consider the gauge being faulty. usually when it shows 10.0 it is the wiring not wired correctly, or a bad connection. or wot fuling is off lol. but somtimes the sensor is bad

 

the sensor is brand new and the gauge shows the same as wit the old sensor so its somewhere between the gauge and harness. i spoke to AEM tech support and he said if its not the sensor most likely its the harness cause the gauges hardly ever go bad

at least yours shows somethin lol

naw, its not the car. i took the sensor out of the car so that way it can only sense air and it still said rich. my car has no black exhaust coming out and it has no issue like its flooded. i triple checked the wiring to the gauge. i even regrounded it be sure. only thing i can do now is take the wire to the sensor out and check it and see if it is melted or anything

 

and you verified the wiring is all correct, meaning the gauges pins and connector are fully connected. i know you know wut your talking about i have just dealt with this many times from people who didnt hook them up right.

 

my aem did something similar except it was stuck at 15.9, then it unstuck itself somehow. don't really know why as it never did it again. only thing i can think of is it was extremely cold that day and it was frozen
