The whole thing is taking time to find as I've been barking at some wrong trees, led down some false paths by red herrings and the intermittent nature also adds to the time needed.

Apart from some bent pins inside the connectors, the wiring harness is in good condition on my car. The connectors on the ECU and EZK units have never been touched by dirt or water, just by a hamfisted mechanic shoving pins inside those fragile contacts on the connectors.

The A/C circuit components inside my particular ECU have not been placed, essentially rendering those inputs a "don't care" in logic terms. Whatever its voltage, it's not getting to the circuits.

So, the bypassing of EZK pin 4, the knock enrichment signal from EZK to ECU, is now awaiting a result. Of course right now, idle is fine, but it always is shortly after unseating and seating the connectors.

To be continued...
