Bro, I had my clutch slave cylinder replaced by the dealership several years ago due to the recall and I had the same issue. It was always at 1200 rpms no matter what gear but the worse in first going from 0 mph. It would go to that rpm then have a big surge almost as if the throttle was hit. It only did it after the install by Nissan. All I can say is: is something to do with an improper install by those half *** mechanics at the dealership. I've recently had my slave cylinder master cylinder and clutch replaced and the problem is gone. Hope this helps.
Edit: in short the problem is something to do with your slave cylinder or the clutch. It needs to be reinstalled or adjusted.

Dude your post tells my story word for word!!! It goes away after a couple of surges. It's not constant but happens every now and then. At 85k miles I'm still on my original clutch (1 owner) so if and when time comes, I'll look into replacing what's mentioned in this thread.

I doubt faulty spark plugs could cause a jerking at low RPM's. If you do decide to change them out let us know if it works.

I don't feel like my car is throttling without my action though. It feels more like the gearbox is dragging. When I'm coasting in 1st gear I feel resistance compared to when I'm coasting in neutral. Keep in mind this is my first manual car that I've had for less then 6 months now so I'm still learning the nuances.

Thanks for confirming. My only personal concern is if the issue I'm experiencing (jerking back and forth at low rpm) is actually the same issue as OP. I plan on getting the Zspeed master/slave cylinder upgrade kit regardless.

lol, this is normal with all manual cars. It's the gear winding down. It's also a good thing as you can downshift when slowing down and it doesn't work your brakes as hard. Try it, it's rather fun.
