hi, i recently bought a 2000 intrepid with a 2.7 litre. i started it up and it ran fine i drove it for about half an hour then i turned it off to get gas and it would only turn over it wouldnt start. then after 15 minutes itstarted and i tried to make it home but it kept on quitting every minute or so then ide have to wait 10-15 minutes. i got it home then the next morning i drove it to chrysler. they put it on the computer but it showed up good they didnt know what it was but they said it was electrical. i then decided to change the battery so i took it to costco and in the parking lot i took the old battery out and put the new one in. when i plugged the new one in the car honked once. i thought nothing of it, i think started the car and it ran fine. i turned it off again and locked the doors and went into costco and bought a hotdog. when i came out i unlocked the doors and the bloody alarm started going off! i didnt even know the car had an alarm! i quickly unplugged the horn fuse and had it towed to my house. has anyone had an experience like this??? i cant figure out why my cars crapping out (reagarding the problem before i changed the battery) and now i dont know how to disarm the security system!! help!
