Exclamation 1992 BMW 525i rough idle diagnosis help

So I purchased a 92' 525i with the five-speed manual for $300 and I went to go and drive it home today and when I got there the car was completely dead. After swapping out the battery I fired it up and it idles really rough. It hunts for the idle for a little while and then the RPM's dip down to 700-600 and it seems like it wants to die. After moving it about 100 feet it stalled. I start it back up and it runs for a few seconds and dies. I do this about 10-15 times and get the same result. Every time I push the accelerator pedal it dies. There is definitely a vibration coming from the engine which I suspect to be a misfire and just bought new spark plugs but have not installed them yet. I will post links to videos of the car in an effort to try to see if anyone can pinpoint what is wrong with the car. I would really appreciate some help with this.
