Standing by waiting to see if I have to replace it. Can't drive it like this.
I had the same problem on my 2002 xterra non super charged. My light came on for the knock sensor. Only thing I did was to tighten my gas cap down, and the light turned off after 3 driving cycles. I hope this helps you. Also try some shell midrange gas, my light never came back on and I'm back on reg shell.
