So I disconnected my battery to replace my abs fuse with one that was cut because I was prepping for a drift event (and I've used this cut fuse before with 0 issues other than the intentional no abs), and when I connected the battery back and went to start the car, it immediately went to redline and I turned it off as fast as I could. I then put the old fuse back and tried again and it now idles extremely rough and high. There are no codes being thrown and it ran great the day before. I attached a video to show the idle. The only thing I can think of is I knew my valve cover was barely leaking into one of the spark plug holes, so maybe enough oil built up and shorted one of the coils? Does anyone have any ideas of what this could be?

 

Disconnected the battery again and unplugged throttle body and maf and let it sit overnight and now it's back to normal, super weird.
