Is my AEM A/F sensor going bad?

How can you tell if it's going bad? Today I couldn't get a reading below about 14 no matter how much fuel I added. I added enough fuel to where it would stumble bad. I eventually just gave up and took the fuel away until it ran good and ignored the gauge. The number goes up just fine when it gets lean still. I run straight avgas when at low elevation and mix 91 with avgas in the mountains.

When mine went bad the gauge just sat at 14.7 and never moved.

According to that test mine is bad. That kinda sucks. It only has around 350 miles on it. Ordered a replacement.

That's what mine did when it went bad. Kinda scary ignoring the gauge...especially when the sled it fairly new to me!
