Well, it turns out it was my fault.
I did a compression test on the engine, cylinder 3 was zero. I removed the valve cover and double checked my valve adjustment. Sure enough, cylinder 3 was completely off. The exhaust valves wouldn't shut. I think I must have done them in the wrong order or something. I readjusted it and it runs smooth as glass now. I'm so happy to have that sorted out.
I finally got to take it for a drive. I must say I REALLY like how the car feels/drives. The suspension setup or something just makes it feel good.
