Which knock sensor?
There are 2 different knock sensors listed for the 98 LS1. Is there any way to tell, by VIN or anything else, which one I have before you get it apart? I never have had to take anything apart on this motor, so I am a little nervous about replacing the sensor. I have many years experience with other motors, cars and harleys. Your suggestions for making it as easy as possible would be appreciated. I think I am just going to replace the front one. Not interested in manifold swap or any other mods at this time. Any tips or encouragement would be appreciated.
