Where are the knock sensor locations for the 1997 S10 truck with a 4.3 liter engine? I bought 2 sensors because the parts store specs called for 2 sensors as did online sources. I can't find the sensors, was told one is located between the number 3 and 5 plugs but I don't see a sensor there. So I assume the advice was for the wrong year model. Please be specific about location.
Thank you.
