I went to the Dealer the other day, and they recommended me to take the FUEL INJECTION AND THROTTLE BODY SERVICE COMBO for $159.95.

What does this exactly do, and is it worth it? Besides warranty, have you guys done any services at the dealer? Thanks

 

don't look like routine Nissan factory service schedule.

 

...sounds a little fishy... I'm guessing the fuel injection service is a fuel injector cleaner poured in your gas tank. As far as the throttle body, I know on the VW's with throttle by wire there is way you can tell the computer check and calibrate the throttle blade postion.
