If you do end up replacing your MAF sensor (which you may just be able to use a spray cleaner) be sure and get an OEM one. This is a device that relies on a specific resistance curve and heating potential, and off-brand sensors can throw things off with your engine as well.
+1 on that also. Aftermarket sensors will usually calibrate okay when you do IAVL, but that's only half the story. The ECM will extrapolate that base reading across the whole RPM range, so if the response curve doesn't match what Infiniti intended, the best thing you can expect is poor performance. The worst can get downright ugly. Don't go there, get the OE part.
