    You need to identify if the sound is combustion engine knock. You did not say what fuel/octane you are running. You may want to increase your octane on a tank load to an "over the top" value just to see if the sound goes away thereby indicating it was in-fact engine knock.

    Once you identify what the sound is & where it is coming from, you can fix it.

    DZ I would also check the exhaust manifold and any other exhaust pieces for a leak. Also check your plug wires, look for any signs of arching. Hope this helps and good luck on finding your problem. :cheers
