I’ve changed all the plugs so 🤷🏻*♂️ I’ll look them all over again tomorrow. 3,4,6 are having miss fires and it’s more on 3 and 6 from what I’m seeing. Just seems weird it’s staying on those ones even with swapping plugs.

When I had misfires, turned out to be corrosion on the coilpack connectors. Maybe check those.

All the connections are good. I’ve checked them more than enough. Not connection issue for the packs, wires, plugs, injectors. Haven’t pulled the injectors yet.
No intake leaks It’s just the same ones over and over even with swapping stuff put some injector cleaner through the engine to see if that’s the cause and didn’t change anything either. Tune at least from my tuner haven’t solved anything. He sees everything looks good other than the misfires.

I have seen where broken valve springs could be causing this issue. Seeing you checked all electrical stuff, You might want to pull valve covers and check.

Not sure how to figure that out lol.
I’m thinking I either have a boost leak, which could be also what you said. Springs are going out, lifters are failing, or push rods are loose. Kinda all the same out come lol other the. A leak someplace else. It’s that’s my issue that’s a easy fix cause I plan on pulling the motor in a few weeks to do the build just don’t want to do a build snd issue is there when it’s finished lol.
