Default Misfire question

So ive been having a rough misfire lately and i hooked it up to my scan tool, and while viewing the data it has a misfire on 4 and 7 at idle around 550 rmp, and then when i hit 2000 rmp roughly it misfires at 5 and 8, until about 3000 rpm, when i have no misfires

Anyone have any idea why the misfire moves like that and then disappears?

All plugs, wires, coil packs and injectors have been replaced

Thanks
