I got access to one at work/but that's not doing you anygood,,,,,researching a bit-seems that one sensor could be picking up a noise & logging it (actual #of times it picked up that signal) and i've also read where moving the mafs can cause unusual noises that the knock sensor picks up.
Jon said he could not determine which bank was reading the 22,800+ times it picked up a signal,,,,not sure why the cel light hasn't came on.
could have a vacuum or exhaust leak......i've been talking to a few of my co-worker's about this & they ask me which bank is doing it.
Also have read that a clutch engagement noise & sudden acceleration of the free flow exhaust can trigger it.....these are on generic cars & not a 370 in particular.
heck-i just remembered an instructor's name/gonna give him a shout.

I don't know exactly how long I have driven with out a tune but a long time lol, Also Tomorrow I taking my car to a buddy of mine who is the Nissan Master mechanic here in town. He told me to bring it to his house tomorrow night. He's going to bring his tools home and find out exactly what the deal is.. He also told me that It could possible be a critter got in there and started chewing on some wires... And as far as a cell code goes he told me the car will NOT throw a code for a knock sensor.. he told me Nissan has it set up to pop a code but no light will come on, and that the knock sensor only reads at high RPMs... So stay tuned and ill update sometime tomorrow night...
