I was just wondering if this noise is supposed to happen when starting up my Kia Optima after it has sat all night? I just bought this car 2 days ago. There seems to be a slight rattle for maybe 2-3 seconds when I first start my car. Anybody else's does this?

I believe you'll find it's the nature of the beast. My wife says she's never heard a car so loud when first started. Propbably the high pressure fuel pump.
