I picked my M5 up exactly one month ago today, and it has over delivered in every way until a few days ago when it started running quite rough. SES is on, power is way down/not smooth and idle is rough. I also have what I've heard referred to as a 'blatty' exhaust note. My Peake was ordered a few weeks ago, but unfortunately I'm still waiting for ECS to ship it. Anyways, I ran up to autozone and had them pull the codes with what I believe was an Actron reader. I got the P01344 and P01345, both of which indicate a misfire on cylinder #2. My plan was to swap the #2 coil with another to see if the misfire follows it. I think my troubleshooting logic is sound, but before I get started I wanted to check with the board as you are all much more experienced than me with the S62. Am I on the right track?
