There is a base idle (solenoid not energized) so the car will shut off without dieseling. This is usually around 500-700 RPM
With the solenoid energized, it pushes the plunger out, raising the idle so it idles smooth.
This is usually around 1000-1100 RPM.



What controls when the solenoid is energized? I haven't had any problems with dieseling, but I have noticed that coming to an abrupt stop, the car briefly wants to stall before regaining it's composure. If this allowed idle to be higher at some times, but lower at others, this might be beneficial, but again, I don't understand what controls it's operation.

Don't feel too bad, lowly '70-'71 340 guys, there's always us '72-'74 guys out there.
