Default getting a cyl #3 & multiple/random misfire code
the plugs look good, but the #3 cylinder has a light brown hue while the others have a slight black tint (running lean?)

i swapped the spark plugs out with a diff brand & swapped the #3 & #1 fuel injectors as well as the #2 & #3 coils.... lets see if it follows to another cylinder

had the injectors flow tested & cleaned no more than a 3 months ago

any ideas?

Were all your plugs in tight, one didn't get loose, this happened to me before..

Did you check the resistance on the coil packs? Worth a try.
