Murano jerking problem (2004 SL)

2004 Murano SL
When going from a stopped position the car has violent jerking with the RPM's rising and falling until the car reaches about 20 mph, then the jerking stops.
Does anyone have any ideas or thoughts on what this could be?

I postsed a video of the RPM's as this is happening-

Just had to tighten the loose air intake hose that supplies the manifold. It must have gotten loose when I was checking the air filter.
