Hello, I'm Brandon - Nissan tech.

Is the check engine light ON?

It looks to me the throttle body assembly and the sensor is bad. This is the reason why the engine is reving up and down. The repair for the throttle body unit replacement with programming is about $500.

Let me know if you have further questions. Please rate me positive, thank you.
