probably a airflow meter failing. It was a common problem on XF EFI's.

I have an XF carb at home from my Dads old series 2 XF & the idle solenoid is vacuum operated so it does not have the wires. Maybe yours is a vacuum operated one & this is why you can't find any wires except the one to the choke.
