go to autozone, ill put money that your alt either going bad, or maby a bad connection from it, but either way it has drained your battery down to next to nothing and now this is where you are

check your idle control motor. it might be clogged with carbon or not working at all. have the computer scanned to see if there are any codes in memory.
