Okay, here's an update since I posted earlier. I just got off work, I figured to try to solve the problem I would let the car warm up. Bad idea. After about 30 seconds of idling, the car started shaking uncontrollably. I turned it off after about 10 seconds of shaking. The Check Engine light is on. I think I'm going to take it to the dealer Wednesday. I would tomorrow if I didn't have to work.
