So I have a 2007 g35 coupe with the revup DE engine. I have a problem, when i wanna do a pull on 5k rpm it pops from the air intake and it like cuts power and then it comes back but it still pops. Idk what it is hopefully you guys can help me.

 

Sounds more like a backfire.

Is the engine stock? Check engine light on?

 

What do your spark plugs look like?
