Relearning idle speed without cleaning the throttle does nothing, because it's the same throttle and same engine, it'll idle at the same plate position, and if you've got a "step" of carbon/grime at that position, it'll constantly hunt around, as on the step the idle is too low, because it's not a smooth bore anymore, but a step, and above that step it'll idle too high.
