2018 SS 1LE Misfire issue, with mods

I have an 18 SS 6MT, it has been modified.

TSP cam, 660 valve springs
Katech ported heads
Corsa headers
Corsa extreme exhaust
LT2 intake
LT5 throttle body
E85 conv.
Roto-fab intake

I have slowly obtained a misfire. Then it got bad enough that it threw a code.
Then it has the 'stabilitrak' code and service 'rear axle' code.

The stuff I have done.

replace plugs- cylinder #4 was showing a misfire and the plug was a little bit blacker than the rest. No change

coils- replaced 2, 4, 6, & 8. No change

noticed that #4 header tube was usually 200 degrees while idling when the others were 4-450.

replaced spark plug wires. No change

then finally replaced #4 fuel injector. No change.

after all if this I did the CRC intake valve treatment, maybe it had excessive deposits (looked at it when I did the injector but did not look bad) No change


Other bits of info. When it is idlin it is fine. When you are accelerating under roughly 20% throttle it pops and crackles, when you are aggressively accelerating it runs pretty good, almost like it should.

I am running out of things to throw at it. Any suggestions?
