missfire help

can anyone help.
i have a 98 m3 evo (S50) which has an intermitent missfire at high rpm when on full throttle, it normaly starts at about 5500 rpm & sometimes it will not rev above 6000 at all.
i have pluged in my scanner to check the fault codes & it comes up with missfire at coil cyl 3 & 4 (codes 24 & 50). i then tryed swaping the coil packs from cyl 3 & 4 with 1 & 2 to see if the fault changed cylinders but it stil says 3 & 4.
whenever i clear the fault codes it will not missfire at all for a few days & then it will do it randomly.
any help would be apreciated.
