I have a 2000 nissan sentra. When I start it for the first time everyday it putters and kinda jumps and then the battery dies. After I restart it, it putters for a few seconds and drives really slow. The battery usually doesnt die a second time and after I start going the car runs fine. Its been doind this for about 3 months and seems to be getting worse. The battery is less than 6 months old. Any ideas what it could be? I dont really have the money to take it to a professional right now.

if its only in the morning that this happens then it could be that you're not warming your car up enough before trying to drive, that can cause splutters as well as a slightly louder engine noise
