Spark plug wires arcing against the exhaust?
Ignition coil issues
06 AWD SS, ignition coils 5 and 7 were not firing correctly. A friend had a meter that links with the frequency of the coils. 5 and 7 had a very rapid frequency. I changed both coils and the truck came back from the dead. Full power, no hesitation and what felt like a misfire was gone. This has not thrown a light or a misfire code. About an hour into putting some miles on her the same issue came back, same 2 coils. Any advice?

You could try swapping thpose 2 coils to different cylinders and see what codes you get
That would lead me to believe that the wiring leading to the coils has an issue
Could be as simple as dirty/corroded/loose connectors
