Well with out you describing what kind of noise, pinging or knock, there could be many different answers to this. I'll stick with the most common problems, bad gas wrong octane .bad plugs or wires, ,faulty emissions system, vacuum leak, or fuel injection system malfuntion . all of these could be your answer but the problem needs to be better descibed. I would start with the easiest firat then move on from there.
