The engine should not quit with the O2 sensor disconnected...it should run just fine. The whole closed-loop system is only for fine tuning.

0 mA at the EHA means that no correction is being made at all.

You should see a varying mA reading at the EHA, not fixed.

Why not try reading the pin 2-3 duty-cycle output on the round diagnostic socket? It may confirm the problem. I believe 10% fixed would confirm Steve's diagnosis of a bad O2 sensor.

What voltage is the O2 sensor putting out when the engine is running?
