I thought fan too but they looked normal, might be that the variance is not noticible on them now that you mention it I did not try it with the AC off. I remember my old del sol, civic, accord and crx suffered from something similar which was beyond annoying on stop lights, it was a coolant sensor, but the tach would move up and down with the variance, i did not see the tach move on the ridge��
