Those are all shot to smithereens (plugs and coil packs). That should clear up the misfire issues!

It seems like the coil packs and plugs did it.
- Ran compression, all hovered +/-5% of 215PSI
- Scoped the bores, pistons were not brand spanking new but consistent... may run some seafoam.
- Cleared codes after installing the coils and the rumble is gone
- Cylinder roughness on all cylinders consistent (C2 roughness down to 0 from 14)
Will go for some italian tuning and see how she fares.... Thanks Hive Mind, fingers crossed.

What brand did you end up going with for plugs and coils? I've got that job coming up soon on mine for the first time, and I'm curious what the board prefers.

I don't know if the brand I chose was the preferred one, it was the Rennline coils on Pelican. All I can say is they work fine.... let's see how they fare after 40k miles. They are larger coils and reportedly "more powerful" and need a spacer / longer bolt kit to push the heat shield back a little bit (sold on pelican). They were about the same price as the Beru or Bosch coils.
