Hey there, I had my sunbird in a car show today, and when I left I stomped on the gas and there was an aweful sound. My car is a 5-speed 3.1 and each gear after 3000 rpm the car makes this sound like something is dragging on the ground. Of course nothing is though. It almost seems like it is coming from the catalytic converter. Has anyone experienced this? It only happens during acceleration. Any help would be appreciated.
