idle drop after stops
Hey, I have a 06 SS/SC that I just got, I have 1800 miles on it. Ever since I got it, about a month ago, when I come to a stop at lights or whatever, the idle will drop to about 500 rpms, almost die, then jump back up to 1500 and back down to 500, etc. It does this back and forth about 3 or 4 times, then it levels off to normail 800-900 rpm. It does this probably 75% of the time. It doesn't matter if I was getting on it or idleing through town, it does it regardless. Its just a little discouraging because its a brand new car. It sat on the show room floor at the dealer where I bought it for 355 days. So, I don't know if sitting so long had anything to do with it or not.
Any help would be appreciated.
