Neutral Idle Revving on its Own
Hi, I have a 2005 350z with 40,000 miles. Today I changed the oil and oil filter, and changed my front brake pads and everything went smoothly. My friend decided to check my air filter, and used an air gun to try and clean around. When I started up the car, everything was fine and I started driving a block down the road. When it was in neutral it suddenly began revving on its own, and I am not sure what is going on. Does anyone have any idea what the issue may be? I put in 5 Quarts of Royal Purple SAE 10w-30, is that wrong?
Here is a video of what is happening. https://www.youtube.com/watch?v=5P-t...ature=youtu.be
I appreciate any help with this, I'm a dummy

Depending on how aggressive your friend was with cleaning the airbox with compressed air, he may have damaged the MAF sensor. Your VQ is surging because this sensor is proving conflicting information to the ECM. Do NOT blow compressed air around such sensitive components.
