Ok i`ve got a `94 2-door Cutlass with this loud banging noise (metal to metal) that occurs after ive come to a stop at a light or sign and then as soon as i accelerate a loud bang sound happens underneath the car in front. THE CAR IS NOT BACKFIRING!!!!!!!!!! everyone ive talked to swears that it is but its not coming from the rear. Sometimes when switching from Park to Reverse or D to R the noise happens there. I thought it may have been the parking brake but ive disconnected it completly and the noise is still there. I need some suggestion about where to look and what to look for and my Cutlass would really apprciate it to.
