I brought the car to my independent shop today, and he said he can't find anything. No codes, nothing that leaks or looks wrong and also on the test drive he couldn't get to that problem (maybe cause I de-installed the COBB).
Look for the DYI to check if you have a bad coil. It's very easy to do. That's what I did and sure enough, I had one that was bad so I replaced it. 30 min job.
