Rough patch issue on some prints

Hoping to get some help with some random quality issue patch’s on some of my prints. I have been having good success with most prints however I’m noticing at random patches of what looks like under extrusion. I’m not 100% sure if this is the case though. I’ve attached several pictures and will try and get some better ones if these don’t help.

I find they are often on the same layer as small overhangs are located like a screw hole. I also notice they are near seams where retract/unretract and wipe occur such as in some of the pics attached, but it is not consistent up the seam. Not sure what details to provide but I’ll try and cover some of the basics:

  • X1C in AMS
  • Different brands of PETG and PETG-CF filament (Sunlu and IEMAI in pictures)
  • All filament dried per standard times/temps
  • .04 nozzle
  • .12/.2 layer height (doesn’t seem to change based on height)
  • Orca Slicer
  • .02 pressure advance based on calibration

In generally these patches are nothing more than unsightly but I’d really like to get it resolved so the prints look better.

Very much appreciate the help in advance.
