(Heh)

The idle controller is officially _supposed_ to be sensitive to electrical 
loads, or more especially battery voltage.  I think idle is supposed to go to 
around 1100 rpm if the battery voltage falls below 10.something.

But I'd still _double_check_ the grounds.

The system is also ludicrously sensitive to intermittent breaks in the ISV 
circuit.
