You could try it but IMO it's a bit of a waste of gas. Eventually it will just reprogram itself. I have never done the idle learn procedure and have no problem - I've disconnected the pre-cat O2 sensor a few times with the engine on too, for shop assignments, so I don't think it's a big deal. I remember the car used to vibrate but that could have been bad gas, or just a temporary thing with not doing the idle learn...either way it's fine for me now.
