I have a 2006 pontiac G6 GTP. I have the 3.9 engine. Just got it. My engine when i am idiling it quivers and shakes the car. I notice a small pinging noise in the motor. changed the oxygen sensors. Going to change plugs and wires what else could it be. It runs good when accelerating though i feel a little loss in power. Please help me out here i am going crazy> Thank You
