Here's a video of my car having some revving trouble. It jumps up and down and when I step on the gas petal there is a delay. Any ideas? Thank you.

The rev problem can be clearly seen 33 seconds into the video.

 

It could be anything that has something to do with getting the engine to breath. Throttle body comes to mind. I see you are at 100k have you done any services yet? I would clean the TB, MAF, change spark plugs, air filter and check for vacuum leaks. Go to advance buy some seafoam and put a half of can in your tank while full so you can clean out your fuel system. It is hard to troubleshoot without codes on these cars but if you do the basics then you should be good with the issue you are having. You have no check engine light so it is probably storing it in the information section until what ever is preventing air actually fails.

Also it seems to me that you are about to stall because you dropped below 500RPMs at one point. You need to check emission parts (Air). I do not know if you have a DISA valve but check that also.

 

Thank you seanjordan20. It was the throttle body. My friend and I cleaned the throttle body and maf sensor. I've posted a video of the results.
