I finally got my car back to stock. I'm having a few problems though.
NOTE: The car doesn't want to start on the MAF, so I'm running in speed density. Also, there is a minor exhaust leak. I haven't had time to fix these issues, but I'm not sure they are the cause of my problems anyway.
1. The car surges at idle, and RPM goes up and down.
2. The fuel trims are reading CRAZY negative values. I saw -40 at one point. Not sure if this is MAF related? I can also smell raw fuel in the car on startup.
3. Engine still makes light scraping noise at around 2000 RPM. I'm not expecting anyone to solve this, but I thought I'd ask anyway.
