This has probably been answered already on another thread but I cant find it. Anyway my car is a 2004 g35 6mt that has had the dash and steering wheel changed due to airbags deploying from previous owner motor was not damaged but it starts fine everytime idles good it fluctuates slightly between 6-650 (it seems kinda low to me but idk other threads say thats normal) when warm. But once warm when idling and you rev to +3k and let off it drops below 500rpms almost cutting out, also when driving while decelerating occasionally it will stall when the clutch is depressed while downshifting usually when using the engine to slow the car so basically making the rpms go from +3k down but while driving it will completely cut out instead sputter and catch itself. At first it would only do it with the ac off now it stalls ac on or off and getting more and more frequent. I need this problem fixed before my gfs driving on the freeway and the car stalls and loses power steering and brake assist and she freaks out or hits something haha my car is basically stock motor wise just an injen cai and invidia cb exhaust idk if anybody has info itll be greatly appreciated.

 

Haha I just was reading the injen installation manual online as I got the car with it and it says that if the lower insulation (which I dont have) behind the bumper in front of the intake filter is removed it will cause the car to stall lmao well im gonna try c what I can do about that and hopefully that solve the problem.
