LTH with HFC + CBE = ?

Just picked up the car and something is up with it and I'm not sure what it is. The idle feels and sounds lumpy like a cammed motor. The lumpiness doesn't go away the more it revs, it just speeds it up. My butt dyno tells me power is missing and the SES light blinks furiously any time I accelerate. I'm letting the computer try and tune itself for a few days before I bring it back and / dyno it. I took a video of me driving home for you all to listen, maybe you might know what is causing it or if it doesn't sound right. I also think I tracked that damn metal resonance to the heatshield that used to be by the cats. I'm going to get it removed and see how that works.
