I think the outside temperature has to be low enough. The days it comes on check your outside temp versus the days it doesn't. I don't have one, but as far as I understand thats how it works.

Looks like someone beat me to the punch...:Thumbup:

As for me today I'm working on a clients computer here in New Meadows, ID. It's roughly about -16*F outside. Once my truck gets cold after I'm done here working it should kick the 3 cylinder high idle fairly easy...

You also got to remember that the grid heater will raise the temp in the manifold so even though its -16*F it might not stay cold enough to trip the 3 cylinder high idle but at least the high idle will hit...

As you might want to check your IAT for accuracy too...
