if it idles fine when warm, the ISV probably works

perhaps, either of those.  If it starts ok and drives ok cold, though,
the WUR is probably fine.

a bad coolant temp sender can make your cold idle troublesome.  could
also be a flaky idle switch.

maybe that ISV is sticking after all...

Stop thinking and start checking... is the idle screw loose?  is it
sealed properly?

What does the coolant temp sender measure, cold and hot?

What condition are the electrical connections under the hood in?
