E36 M3 Check Engine Light?

[tooshfty]

Hey guys, I finally bought a code scanner for my check engine light. It says there is a misfire on cylinders 3 and 4, giving me specific codes that I will post down below. So I guess they speak for themselves for the most part, but I am wondering what it is exactly I have to replace? It says $12 generic so does it want me to replace plugs? Just basic info, the spark plugs were replaced over a year and a half ago, and ignition coils were done 2 and a half years ago. So I feel I may just need a tune up, what are your thoughts?Screen Shot 2016-01-27 at 2.24.04 PM.pngScreen Shot 2016-01-27 at 2.23.56 PM.pngScreen Shot 2016-01-27 at 2.23.40 PM.png

swap coils to cylinder 1 and 5 see if the miss fire follows if it does buy new coils. How old are the plugs? what brand of plugs are in the car? when was the last time they were changed?

Not sure on brand of coils or plugs, but coils done over 2 years ago and plugs over a year and a half old. Any recommendations on plugs or coils? I was thinking of going to turnermotorsport
