where is the knock sensor on a 1989 Chevy s10 Balzer (4.3L 6-cylinder Throttle Body Injection engine). I'm thinking of replacing it because I've replaced almost everthing else but my "Service Engine Light" stays on after driving at highway speeds.

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on.
