Hi guys,

The car is running out of warranty in 3 months (08 G37 with 23K miles) and sometimes it goes into limp mode (rev hesitation) after some driving. FYI, recently I changed the engine fuel regulator and this problem started happening right after. Taking it to the dealer is the next step if I could reproduce it during the day when the stealership is open.

Here is a video from the dash showing the rev. hesitation in park:

Not sure if reprogramming the ECU will take care of the issue. Any suggestion is appreciated!
