Two thoughts on this: I, like Bruce Benson, had two of the early versions of the J&S knock sensor (infact, I had the very first one desined for the PRV odd-fire engine). My experience with them was the same as Bruce's. I finally yanked them. Last year I found that I "ran out of power" at higher rpms. A new coil (Bosch) fixed that.
