2008 350Z Touring 5AT
So I've had this little annoyance for a while, maybe a couple months?
When the engine and all is at normal op temperature and I start it up, it starts every single time no problems. But as the RPMs settle to idle they tend to drop to around 200 RPM (almost like trying to stall) then catches itself and bumps back to idle 500 RPM. It's almost like a smooth wave when it does this.
It's really nothing obvious, except to me. Only time it doesn't do it is when I apply just a slight push to the pedal to give it a bump before it rests to idle. And doesn't do it on cold starts.
It hasn't gotten worst, I'm just curious if anyone knows anything. More of a slight annoyance really. I like my Z to be "perfect"

Perhaps a few things to look at in this order-
Air filter, dirty MAF sensor, dirty TB, intake air vacuum leak, open/malfunctioning intake manifold coolant temp sensor. GL!

Well in all honestly, it is time to clean and re-oil the filters, and I do hear hissing in the engine bay time to time. Thanks for the input brother
