I have been looking in all the usual places, and I have worked with knock sensors so I know what the old ones look like. Where is it? Mine is not working. I installed a superchip last year and my truck detonated horribly w/93. I removed the chip and it still detonates on 93, not as bad though. I have had the chip reprogrammed and it is better but still not perfect.

Under the intake, harness comes in from rear of engine just to rear of #2 and front of #7.

 

What is this knock sensor? I have noticed mine knocks somtimes while getting on it, but I assumed it was just bad gas. Is there somthing I can do to fix this? BTW, what kind of gas do you use?
