I installed a JWT pop charger aboujt 6 months ago. Now that the air is colder, I have rough idling (around 600 rpm). Before I take it to the dealer, should I swith back to the origianal intake? Also, is the cold air a big factor in the rough idling?

 

check for airleaks.. or loose maf connector. its most likely an airleak. Also, clean ur filter if u havn't. I doubt it has anything to do w/ the popcharger construction. If it all fails. put on the stock airbox

 

If you installed the pop charger 6 months ago, and are having problems now, I doubt if it has anything to do with the pop charger. I’ve been taking evening cruises with the temperature below 32 degrees, and the 350Z loves freezing air. BTW I doubt if any adjustments are covered under warranty.

 

n/a motors thrive on cold air... is it just the idling or also while ur driving that it's rough, etc.?

 

It's only rough at idle - around 600 rpm. If I give it just a little pedal like up to 800 to 1000 rpms, it is perfectly smooth.

 

have you ever cleaned the filter?
