So I hung a long wire off one of the unconnected A/D inputs, it's just as flat as before.
But the A/D input connected to the pressure sensor now has the unexplained rise/drop at a different time. It shifted with DST going away.
I guess isolated power supply is the last step now. Or an RF box around the pressure sensor.
