Thanks everyone for the suggestions. Before I change anything I'll hook up my vacuum gauge next to my tachometer and a/f gauge and record a video of the issue I'm having. That might help get this sorted out. I'll also post answers to some of the question that were asked in this thread. I should have a video of it in the next couple of hours.
