My supercharged gtp stalls randomly. It has been acting funny for a few months. When i brake hard, it shutters and acts like it's trying to die. the tach goes crazy, then it goes back to normal idle. Yesterday, after a short drive, as i'm pulling into my complex, the car just dies. I restart, pull forward 3 feet and it dies again. I restart, and same story. I pull into my spot and during the task it dies three more times. Then i finally park it and let it idle. It idles normally. Nothing sounds crazy. Also, my "tcs off" light comes on at the time my car first died and it wont go off when i press the button. Any ideas?![]()
