I just got injen cold air intake for my 2004 g35 coupe and it idles very low it around 500 rpm is that normal i also have stillen exhaust if its to low how can i raise it or fix it???

 

The dealership can't adjust the idle, but from reading another post the other day, they can advance your timming to achieve the same results. Not the best option, but it is an option.

It's not stalling on you, is it?

 

it was stalling when i dropped it into neutral when i was at 6500 rpm but i got a heat shield for the intake so it doesnt do it anymore but, is it bad for the engine to idle so low

 

that is around normal...500-600...mine sits at 550-600
