I have a 2012 RSS SE5 with 2BRO exhaust and Juice box pro with under 10k miles.....It had been sitting for about 2 months,When I started it up it sounded like it was only hitting on one cylinder,until it started warming up and the miss went away,....I thought maybe gas was going bad so I ran some lucas fuel additive through it and a couple of tanks of gas....But still the miss persists.(only at cold/start up)I havent had time to dig into yet,But was wondering if the ECM would detect a missfire and throw a code?
Thanks in advance.
