M50 idling rough and stalling

[Eldobot]

These clips are from the day before of how the engine is running, seems to be a misfire but I would like more opinions. Today I had to fix the ground wire from engine mount to chassis because the car would not turn back on when hot and alternator was not charging battery. After fixing the issue the idle is even worse and stalls after running for maybe 10 or so seconds.

The videos are before ground wire change and before worse idle. Any help is appreciated.
