Mar 2013   Car was hard to start in the morning. Cleaned throttle body and the car started as usual. It is important to have the ECU relearn the idle otherwise the Check Engine Light will come on. Procedure can be found here http://forums.nicoclub.com/help-relear 
May 2013   After cleaning the throttle body, I was not able to make the ECU "relearn" the idle. Had to take it to a mechanic who used Infiniti computer to reset the idle speed.
