im currently having issues with engine missfire on start up. the past few days the weather has been colder and since this colder weather has come so have the missifres and the CEL comes on but it doesnt flash like ive read. ive had missfire on cylinders 2,3, and 4. the car feels like crap when i cold start, my current mods are the K&N intake, catless dp and the e85 tune from Trifecta. been running full e85 since it was released and havent had problems until now. once the car is warmed up and i drive i dont have any issues with it as far as WOT or nomal driving at that. so is it the cooler weather thats causing it or should i be concerned about it??

 

Mine started doing that a while back. Changed my plugs and the problem went away. But you're running E so idk if it's the same problem.
