as i was coming home from work today...my maxima felt kinda slow...slow of the line slow on the highway...
anyone know what this could be...bad intake..??
i'm gonna put my stock air box back on and see what happens...

 

i would look to check for any loose connections on the intake. maybe clean your throttle body. i saw someone comment that this is the most tempermental car they have owned. one day it feels great all around then other days, it feels just so so.
