That brings up a good point about cruise, I dont know. And the AC part I've seen it before and cant explain why it happens. The afr varying from 14 to 15.5 is not that bad a little bit wide than you normally see with properly functioning closed loop. The hunting idle is the weird one. I wonder, when its hunting idle is the spark advance changing or the throttle plate position changing.
