Out cruising the other night I punched it and the car pulled very strong then while shifting into 3rd I here a loud pop from under the hood and a light puff of moke comes out the tailpipes. I did not catch what was going on on my scanmaster and I did not want to try it again. What are some of the typical causes of Popping at WOT? If there is anything else you need to know just ask. Any help is greatly appreciated, THANKS
