multiple misfires could bog you down quite noticeably

Check the COPs

I agree with you.
My miss fire issue was lose cop's (wiggled too much on bolt that holds cop down)
Could also be a crank sensor or Maf ?

If he did a PI swap he more than like doesn't have COP... unless he converted to that as well. Could be bad spark plug wires and or coil pack.

Unplug the cam sensor and see how it runs.

a COP is a coil on plug. since you did a pi swap then you should still have coil packs with wires coming from each pack going to each spark plug.
