Big update. I was driving the car and it was doing it's normal surging in first gear, but something new happened. It started smoking like crazy. Come to find out the ground wire on the #1 coil backed itself out and shorted out on the coilpack. I think this really has to be the issue at this point because there's literally nothing else that could be causing this from all the research I've done.

Anyhow, I plan on picking up a new wiring harness for the coils this weekend if all goes well.
