My car is a 2003 350z with around 121,000 miles. In the video I show exactly whats wrong. I replaced the cam angle sensor but the code for it keeps coming back. When I clear engine codes it will rev no problem, but after a few seconds it starts to hesitate and seems like its going into limp mode. the only thing is it will still rev when its breaking up just slowly and choppy. I replaced the battery ground cable as well as it looked pretty shaggy.

If the code keeps coming back, the system is continuing to detect a failure. What brand of CAS did you purchase, and which code(s) shows up?

I purchased an oem nissan sensor. It keeps reading P0340.

So, how did you determine WHICH cam position sensors to replace? Your resetting the codes technically should do NOTHING to improve the running condition as OBDII is merely the "reporter" of the fault, not the cause of the fault.

P0340, while relating directly to one or both cam sensors, can be triggered by a bad crank sensor or also a board fault in the ECM. I would suggest you take it to Nissan (or independent tech with proper tools) and have them run diags on their Consult 3, the only way to truly dig into all of the levels within the ECM and/or other sub-systems.

Is this the same exact behavior as before changing out the cam sensor?
