I have an '05 GTO with 69k miles. It drives fine, and the car feels great and pulls nice when driving normally. However, when I punch it there's a knock and I can see thin smoke in my side view mirrors. The smoke almost looks like a cloud of dirt. I tried revving my engine at idle, and it sounds fine and doesn't smoke. It only happens when there's a load on the engine. I only use 93-octane, so I know its not the gas. You guys have any input?
