My '04 Cayenne V6 has 65K miles. The Check Engine Light has not come on. When I start the car cold it has a slight missfire that goes away when warm. When warm after start it idles normally for about a minute then there is a noise that sounds like an intake leak. If I rev the engine the noise goes away and slowely comes back. Here is a video...the noise start up at about 50 seconds in. Any idea what this could be? I recently changed the primary fuel pump and fuel filter. I am concerned that the low fuel pressure from the failing fuel pump caused this issue with a missfire or detonation.
