You were right, my cylider #2 plug has a hair line crack out of the box. It's impossible in my opinion to crack a plug because my socket almost touches the sleeve in which the spark plug rests so it can't be cocked. I'll get ECS to replace the plug and all should be good.

I moved the plug to #3 just to be sure and the problem hasn't resurfaced yet, but that has to be it. By the way, I took her out and hit 20psi solid in 3rd-6th gears. It hasn't done that in a while due to the other intake leak I found while troubleshooting this problem. The power and sound of the air rushing is a rush.

 

I got my plug from ECS and put it in today. At the same time I changed the TBB to a Samco, but I don't see anything wrong with the old one. Car runs great so far. We'll see if it comes back.
