Remember that the problem the diagnostics isolate is only the symptom, not necessarily the root cause. Check your ECU connections, and grounding as well. Also check the torque you are using to snug down the knock sensor, as this is critical to its operation.

I had a problem on my '83 where I thought the knock sensor was bad. Turned out the ECU was not providing the proper supply voltage to the sensor, so I needed a new ECU.
