fluctuating rpm idle
at idle the rpms on my 03 max fluctuates a tiny bit. Like it wont stay dead on a mark but will go up down, very slightly constantly. any clue? plugs are new, new pcv valve only use 92 octane. normal maybe?

Check the PCV valve for leaks, etc. Let's face it, the VQ35 doesn't idle as smooth as its 2988cc counterpart.
