Subject: [928] Throttle Switch Test

For those of you who have the late model digital instrument panel, there is 
a quick and easy check to see if the idle switch on the throttle is 
functioning.

While driving at highway speed:
Change the display to instant fuel mileage.
Lift off the throttle completely - the mileage should go to 90.0 mpg.
Step on the throttle very slightly - the mileage should drop to somewhere 
in the thirty - forty mpg range.

This works because one of the functions of the idle switch is to cut the 
fuel completely above 1200 - 1500 rpm when the throttle is at the idle stop.
