I have an 05 neon. I hadn't driven it for about 2 weeks. Very cold weather. I get back and the battery was dead. It was at 2%. I got it charged. Then when I tried to start it, it struggles to turn over. When it finally does with the press of the gas pedal, it roughly idles between 700-1000 rpms for about 3 seconds then shuts off. Any advice?
