My battery went dead on me yesterday and I jumped it off last night and let it run for about 30 minutes. I then shut her down and fired her back up to make sure the battery had enough juice for the next morning. Well the next morning the battery was dead and I had to jump her again. This time once I started, the idle jumped up to 2k and would not back down. Even after the motor was warmed up and being drove the idle still stayed high. While in Drive and sitting at a red light the motor is still turning at close to 2k. Where should I start looking???
