F30 Engine Stuttering--What is the cause?
So yesterday and today when I was on the freeway, I noticed when accelerating a couple times of my engine stuttering..
Yesterday I thought it was because my oil wasn't warmed up, but I felt it again today and it seemed like it was already warmed up..
What would cause this?
I have 2012 BMW F30 335I, JB4 Stage 1 and Meisterschaft exhaust..
