Once in awhile, when i step on the gas, or rev the motor in park, i get a intake backfire, and a little studder. It doesn't happen all the time, once in awhile. I have new plugs, wires, and GM Opti. I was throwing EGR codes last fall before I put it away, so i took it off and just cleaned it. What could it be? EGR? Does the EGR work in Park?

Help!!
