Try disconnecting the O2 sensor, see if that smooths out the idle. I
had a similar problem. That stopped it.

Another thing - in my experience - that will affect idle is the
crankcase breather vent tube to the AFM.  They tend ot rot on the
underside and once there is a hole, it will affect smoothness of engine
operation.
