YOu must have 2002 or 2003 altima. I agree that it might be the cvtc actuator/camsprocket but I am not bothered to replace it since it doesn't harm the engine. Only 50% of cold startup do that. There is a recall for VQ engine the CVT sprocket but not for QR. It could be : CVTC sprocket, selenoid, or timing chain tensioner+guide. Its better to replace all of them because the labor cost $$$$.
