Fuel Cut?

2003 stock with only cat back,

NEW PLUGS AND WIRES.

Ok new problem, it seems to only happen at high rpms 4500+ when im WOT its like a fuel cut or misfire, swapped out coils still there.

Next step test ideas.

it only happens at WOT so if i easy into it but not fully i wont hit that, well almost
happens every time in 1st gear. Its like a back fire but many, like a machine gun but not that loud.

Cant really make a video of it because you cant really hear it, also no codes CEL lights or anything.

Hope its a simple fix. Thanks.

EDIT:
ok so its for sure not the coils, $175 and 2 new coils later still have the same problem, but got to return them at AutoZone, stupid girl didnt even check to see if it was used.
Idea!!! need them.

Kind of sounds like it could be a boost leak. Check that 1st to be simple

Boost leak would cause that?

could be one of 2 problems 1 youre hitting fuel cut because your overboosting in the cold weather. or 2 your BOV is leaking
