Sometime's when I start my car, it turns over, but dies. Sometimes when I start it, it'll run just under idle, and OTHER times, a belt will whine. I'm not sure if it has to do with my sound system, my new exhaust and header or what. Here's a link to a video I posted on myspace of the whining sound if someone could be kind enough to take a look at it. Thanks in advance.
