I could feel the misfires when stopped at a red light, so I fired up the Torque app. 423 misfires on Cylinder 2 in a 60-mile/1 hour drive (mostly highway/interstate). No codes/CEL.

Swapped the packs around to test #2 and misfires still persist on #2.

HKS plugs are only 2-3 weeks old. Cyl 2 plug looks fine. Swapped 3 and 2 just to be on the safe side.

Cyl 2 still misfires. What is the next move? Anything else to check before I get screwed at a dealership?

Just FYI, I was wrong. I did not read the app correctly. Misfires moved from 2 to 3. Couldn't figure out what was wrong with the plug. Just happened to turn it upside down and the cone/insulator (Not sure what to call this part?) was moving freely/blocked the electrode.
