potentiometer

Hi everyone,

I am confused about the function of the air meter potentiometer (86 5kcst).
My Bentley diagrams only show it connected to board computer as a mpg
sensor, while there is no reference to it as an input to ECU. I found it
broken and would think it may cause the beforementioned high idle. Your
expert opinion would be greatly appreciated.
