RUMBLING NOISE IN INTAKE ON START UP.

Chrysler Concorde

Chrysler Concorde, 2002, 95000 mi, 2.7ltr. There is a rumbleing noise which seems to be coming from the intake area only on cold starts and lasts for about thirty seconds. OBD2 scanner reads " evaporative system" not ok.

Try the fuel pressure regulator on the fuel rail, may not be returning unused fuel to tank.
