Help - knocking and one code

Help - knocking and one code
I have a 2008 mustang gt automatic (had for a few months)
Whenever I ride in 1-2-3 for awhile my motor starts knocking but whenever I cut off the car for 10-30 seconds and turn it back on the car runs fine.
My altenator is going bad!
What could this be?
I have replaced
VVT Solenoids,
Camshaft position sensors
Coil packs
spark plugs

Have you scanned the ECU for fault codes?
A video of the engine running with the knock might be helpful.
We need more detail 'cause your description is too vague to make a diagnosis over the internet.

The only code ive ever gotten from the knocking was P0316 And it only happened once when i had to drive with the knock to move out the road to cut off my car, Whenever it happens I instantly shut my car off because it sounds like my motor is going to explode. If I can catch a video of it i will post it, Just dont like it running with the knock because it sounds terrible.

Seems like You have a misfire and yes those can sound like knocking. P0316 is usually coil or coil circuit related. (P0306 would be mechanical).
Did any of your plugs look really oily or just black when you replaced them?
Swap the coil in cylinder 6 with one of the coils from another cylinder. Clear the codes and drive it until you get that sound/feeling. Does the code follow the coil? If it doesn’t, then most likely something is wrong with the wires going to that coil. If the code follows the coil then you have a bad coil.
Hopefully you bought a name brand coil (motorcraft, Bosch, standard etc). Duralast or other no name brands are junk.

I added to your title - just posting "help" doesn't really elicit many responses because people will skip over that type of header. And for later searches "help" doesn't do anything for a search for an issue.

I bought some type of flame masters coils that retail like 13 a piece from autozone, Does it matter if the connector clip to the coils are broken?

#1 cylinder on ford RWD is almost always passenger side closest to radiator.. 5 is Drivers side closest to radiator. This is correct for Mustangs.
