Bobster999, I got the inspiration from your post but I dont want to alter those wire near the ECU so this is what I did.
This is my first time to contribute a post/reply but long time lurker. I had this P0330 code too. This code detects knock on your bank 2 w/c is the radiator side
I did it the hardway by changing the knock sensors, after putting back everything, the code came back in 10min of test drive. I changed all sensor, harness and gasket. SO my next option is to hack this P0330 code AS I DONT WANT TO REPEAT THE WHOLE PROCESS of opening the top of the engine. Since I have the old harness I did the splicing at the harness end and now I dont have code, the car can go overdirve again,,,, but I can hear knocking/pinging/rattling in the engine when it needs more gas or when I accelerate
I read some where that knocking is bad for the engine and the way to remove knocking is to increase the octane level of the gasoline you put in the gas tank. I already am using 93 octane so now I add NOS octane booster and/or 108 octane booster, every time I fill up,,, and knocking is diminished but I can still hear it once in a while when I enter the expressway vaguely.
My verdict is that the knock sensor is detecting a knock in your engine that is why we got the code to begin with, replacing/hacking the sensor might help your situation but the knock is still there. and you might need a mechanic to fix this eventually by adjusting/replacing the valves or piston or something else. I am not a mechanic so I dont know. I dont want to buy a new car either
If what you hear is actually the valves from pre ignition, then you would be the only one. That makes me think that thats not your real problem. Think about it, why only you? I drive mine however i want to with no noise. And I only use 87 octane.

Holy Crap! This actually seemed to work! I had the follow codes: P0171, P0330, P1135, P1351, P1354 Now I only have P0171. The car is running so much better now and it will shift into O/D! Thanks a lot Bobster! I owe you a beer!
