And the misfire, I'm pretty sure that its caused by the lean idle, its very lopey and rough at idle but instantly smooths out once driving.

After my Jdm swap on an 02wrx I had very similar issues.

I replaced front o2, maf. Fuel filter.(none worked)

Replaced injectors and fuel pressure regulator. This fixed the issue. I had the same symptoms. Also I would check your IACV this might be the issue for the looping idle(possibly).
Although, a boost leak could create similar symptoms.
Hope this helps
