Anything ever come of this? I am getting p0325 and 330 for the knock sensor on bank 1 and 2. I just had both sensors replaced when I had my spark plugs replaced. There is 144k on the truck and that was the original plugs. One was actually cross threaded from ford and it finally worked its way out and was leaking making a ticking sound that seemed like it was coming from the bottom of the motor inside it. After the plugs and sensor change I picked up the truck and I still get the 2 DTC's as before. I am going to have him check the wiring I guess (ohm). I am also getting what I think is some pinging sometimes...sounds like something rattling...currently I just loaded a VMP 87oct millage tune and have 93oct in the tank. It made this sound before plugs and tune but it drove so bad I never tried to figure what was causing it.
