It is a rather strange reading. Check if the Megasquirt responds as normal on a Stim and check the wideband's output signal with a volt meter. That should clear up what is going on. What sort of WB is it?

You may have just plain worn out the sensor. In that case it wouldn't hurt to try seeing if you can clean off the carbon deposits with a propane torch. Unfortunately I don't know of any tricks to diagnose an AEM, other than seeing if its gauge matches MegaTune's reading. It may be time for a new sensor.

My LC-1 sensor recently started reading very erraticaly, albeit not as consistent as that, but after a full sensor and heat calibration it is working fine again.

Worth a try if its possible with the AEM sensors

hmm looks like my lag factor went to a default value of 60
used to be set at 85, i wonder if that could be causing this?
