My motor on my 89 SC started knocking, it usually starts doing that before the DIS module goes out. So I ran a Diagnostic and it read code 74- Insufficient MAP/MAF/Baro change during goose test or dynamic response test, code 73-- Insufficient throttle position sensor change during dynamic response or goose test, code 25-- Knock sensor not detected during dynamic response KOER (which I just replaced the knock sensor). where does the wire from the knock sensor go?, Please point me in the right direction, would all these symptoms contribute to the knocking???
