Missfires on cylinder 3, 4 & 5

[N54_E82]

Hello ive been running my car on the highway and I've gotten a mix of cylinder misfires for 3, 4 & 5. At first i got cylinder misfire for 3 cleared it. Days later cylinder 3 didn't come back but cylinder 4 came up, then i cleared cylinder 4. Days later cylinder 3 & 4 both came up. After i cleared those codes i drove the car and cylinder 5 came up. While having all those codes 2a1a tank venting system came up i don't know if this could apply to the misses but any input would help. Also please don't recommend changing plugs and coils they are all brand new and gapped correctly. Also i have just walnut blasted my car so i don't believe my valves are sticking due to carbon build up. All the cylinder misfire codes have came separate and never at the same time except for 3 & 4. I will be moving injectors for cylinders 3 & 4 to cylinders 1 & 2 and vice versa. I also have changed injectors 3, 4 & 5 so i dont know what i could be.
