Another update. I've taken the car on 5-6 runs and the check engine light hasn't come back. However, I'm experiencing a slightly rough idle and slight hesitation around 4k (almost feels like power surges). Looking around I found someone on the pelican forums with the same issues.

I checked my fuel trims and they are almost identical to what this person had. The fix for them was a new MAF. I'm going to order one and give it a shot.
Note: I also did the oil cap test. I took it off with the car idling. I was able to remove it no problem and the car immediately began to run poorly....so I think the crankcase vacuum is okay.
