Wideband acting like tachometer

My wideband has never fully worked, and after finally getting my engine dialed in, I am sure the readings I'm getting are not matching the actual readings. if I turn the ignition on (engine off) the gauge starts at 14.7 goes rich a little, then shoots to full lean (---), nothing too out of the ordinary. But when I start it, It stays on 14.7 for a couple of seconds, then slowly creeps down to 11. But as my RPMs rise, so does the ratio. At cruise, it goes up to 15.4. but if I give it a good amount of gas, it will go higher, sometimes to full lean if I floor it. I'm not sure if this a faulty sensor, or if I got a pinhole somewhere in the exhaust upstream. My sensor is also located in the right area.
