I need help trying to find a glitch. Every now and then my engine light will come on, but it never stays on, I have found that the code is for the knock sensor. The sensor is brand new, but the wire might be shorting. It usually only comes on when im at a stop light. The timing is noticeably retarded, but it goes away a few seconds after i drive and the light goes off. If anyone knows how the wire is routed in the harness, any help would be greatly appreciated
