Low idle. Normal?
 

Enforce I get flamed... Did research but nothing I found really relates to my concern so please come ease my worries here. I have 2004 g35 coupe AT. The car runs really smooth, no stutter or shudders. But it idles low compared to what I've been reading. It idles at 200 or 400 depending on outside temp. But more often at 200 here in the Colorado weather. Again the car does not stall out nor does it give any signs of it. Should I be worried?
Also if I use manual mode and rev past 4ooo I hear a whistling /sucking sound. Is it due to my CAI? I sprayed carb cleaner in the bay but hear no vacuum leaks. Any help appreciated

Anyone have this issue? Or ami just over worrying. Should I think " if it's not broke , don't fix it." Or be proactive about it

Mine does this too (low idle I mean). 04 coupe 6mt in san diego, ca. I'm not worried about it.

Really... I hope it's all good thanks for the feedback mate.

Same situation
 

I got a 04 g35 6mt with 98k n it's idles at 200. I wouldn't worry. Do you have a intake or k&n filter? I hear mines around 3-5k rpm. It's just more air flow though

Yeah I have a Fujiyama CAI ...

Fujita... Auto correct sorry
