Hi guys,

Need some advice. I know its not a g37 but i have a 2015 q40 with 150k and im having some accelerating issues. when im driving but not at start off but when get around 2nd or 3rd gear maybe 4th it struggle accelerating. It hard to describe but its almost like its chugging along. The kicker is lets just say i drive it for a while like a hours or 2 it doesn't do it. i had many answers like fuel filter and throttle body. I don't know if anybody experience this or have and better idea whats going on.

Thanks!
