Day 1 of Spring Break, pulled the LAF Sensor. Looked like this
I don't see anything remotely serviceable...Save for the carbon dust on the end, I don't see any real fouling or anything that looks like it could have killed the sensor. Old age I guess did it in. Going to dig out my ElmScan tmw and hook it up to see if the 02 is doing anything at all. Else time to call up Majestic Honda again.
