Resetting the ECU cleared this up for me and it never returned, this was a few years back. Good luck.

Someone here showed me a TSB for this issue and I took it to my Infiniti dealership and showed them the TSB.

They said yeah it's a known issue and took my car around back, flashed the ECU and asked me to test it out, slight hesitation is gone.

Seems like something in the ECU was the problem, maybe how it's linked up to the transmission or something, but for $50 bucks my issue is gone and never came back. I did get an additional bump in MPG from cleaning everything, but in my case the ECU was the culprit.

When you say flash the ECU you dont mean lile a ECU reset by killing the power for 30min or the reset with the pedal.. you mean like flash/update from their system right?
my car does the same thing at operating temperature only and only on Drive or Reverse. I could chase the problem by keeping my foot on the brake and gas keeping the RPM at 900ish it always does it even after a ECU reset (by killing the power for 30mins)
