You said you returned it to stock and it didn't die at all?

Yes i returned it to stock to see if it was a part that was damaged, however all was fine and it worked without an issue.

How do you have the MAF positioned? I know on the VQ30s MAF positioning actually will make a difference, but I'm not sure about VQ35.
Do you have access to an OBD-II scanner?

Im actually thinking throttle body positioning as it seems that the butterfly valve is either remaining closed or not positioned well enough for the extra air that is coming in from the intake.
I've failed with the attempted ecu and tb reset, so i'm going to take it into the dealer to get it done.
There's no CEL that appears, it just comes on with the other lights as the engine stalls itself, just like when you switch your key to on, but not start.

I also had a similar problem after installing the Mishimoto intake. Immediately after install, the car would stammer and cough at low RPMs. To fix it, I reset the CEL light using an OBD diagnostics unit and also checked the connections on the MAF sensor. I think it was probably the MAF connection that was causing the problem as it ran fine after both of those fixes. You might also check the PCV hose connection on the underside of the intake tube to make sure it's properly connected and sealed. Hope that helps you. Good luck.

Thanks man!
Everythings been checked and i even took it into the dealer to get the throttle reset and relearned and the ECU reset.
It runs fine and is only occurring when i roll in neutral when travelling faster than 50km/h.
So i dont know why its happening, but i've just changed my driving habit to accomodate.

Also, note that the brake pedal method doesn't do anything, except waste time, reset your radio settings, odometer, etc - just useless.

I am about to replace the exhaust and add a Plenum spacer and a Popcharger. Which of the 3 resets do I need to do? Just the first on the list or all 3?
