1) Air flow sensor replaced.
2) clean the all the related air flow pass in included air opening.
3) new plug
4) Computer tuning (damm expensive)

Problem still there anyone enconuter this problem? My current RPM tuned high without aircon on is 900rpm... Need help any sifu can recomended or any good work shop.

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

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.
