 It's actually misfire on cylinders 1-3.  I would start with just pulling the coils & plus and replacing the plugs.  clear the codes and then take it for a drive.

Woah there, calm down, I forgot about the general misfire 000 code. I actually have experience diagnosing a misfire I've just not yet bought/worked on a 986 and don't know if there's another common issue that could cause half the cylinders to fail, hence deferring to others
