knock sensor is not hooked up everything thing else is .. The knock sensor I have no idea what to hook it to I thought it was the oil sending switch.. it has a yellow wire cut off going nowhere. right now...
you will have to find the wire in the harness!
i know for a fact that if the knock sensor is not hooked up or bad, your gas mileage will suck real bad!
i think i got about 5mpg when my knock sensor went bad!
