Have you tried cleaning/checking your ICV, DISA, and MAF? Do you see any smoke? Before you go on a wild goose chase spending money trying to fix it, get a compression test done. I had a similar issue with cyl 5 a while back. My CCV was starting to go bad so it was throwing oil into the cylinder and causing misfires. Then it finally blew the diaphragm in the separator and I had it change and problem solved.
