In retrospect, it seems like a lot o things caused hot start idle problems.
My van has that fan, it would come on about 5 minutes after a very long ride, in very hot weather. Any idea where this van is located? I've heard it over the years, know it exists but never saw it. I cools the injector rail and head IIRC to get excess heat out of there. I don't recall hearing it once this summer, but I didn't go on any trips long enough to trigger it. So it is not uncommon for it to stay off, at least in this van.
I was discussing the fan the other day, and trying to explain it is not near, in front of, or aimed at the radiator in this vehicle. In fact it has nothing to do with the radiator.
Something else I'll be adding to my list, along with talking with the last tech that worked on it.
Thanks!
