I wanted to post an update to see if this symptom may or may not shed any additional light on the miss at idle that I'm having:

The car sat for the last 3 days and upon starting it for the first time again, the car began missing A LOT (It was clearly not firing on all 8 cylinders) It ran poorly for about 30 or so seconds and then stabilized to its usual idle. This incident points me in the direction fuel delivery, possibly a leaking injector. Anyone else have any insights on the issue?
