This is my eleventh corvette, i think i'm hooked. i just bought a 2006 z06 yesterday with 1570 miles. When i first start it i hear a weird noise for about 10 seconds, then it goes away. Could it have to do with fuel pump or some type of selenoid. Just trying to find out what the hell it is. So far the yellow z06 is WOW. Totally bad ass, and i'm almost 53 years old. I feel a hell of alot younger going down the road. Rich
