So I reversed out of a driveway and then threw it in first and floored it (maybe it's just me being a teenager??) anyways i heard a loud bang (maybe from the rear?) and now the car won't start completely. I heard the engine start but it doesn't stay for more than a couple seconds. My friend and I were able to push it while in park and drive. Does anyone have any idea if it is the driveshaft or transmission or some gear or what? I drive a 92 Tbird LX 3.8l v6.
