I'm still working on my engine rebuild on my 1995 VG30E but it's taken so long my memory is a little fuzzy on some of the things from disassembly.
I'm staring at that bolt hole where the knock sensor goes and can't remember taking it off. I also can't find it in my parts pile, but that doesn't mean that it wasn't there.
So my question is, was the knock sensor optional? If so, how do I tell whether my pathfinder needs it? Or would I be better off to just install it regardless of whether it had one before?
