I went by the local Auto Zone to diagnose service engine soon. Came back with a code for bad knock sensor. I purchased a sensor thinking I could find it. I can't. Where is it and how hard is it to replace. I have worked on cars (had to with the bombs I drove) but have put the tools away for a while. Any help you could give would be great!! Thanks!
