2) clean the all the related air flow pass in included air opening.

Is the AFM new ? If not, change new. Its cheaper in the long run.

Good luck.

Its idle dancing common Nissan problem. Yes, clean out the IAC valve it will solve the problem but make sure you seal the flange with sealant or else air will leak all the same.
