O2 sensor - ECU - EHA. This loop fine tunes your mechanical injection. Idle, running, and most functions should run fine - not excessively rich - with the loop open. If running does NOT improve with the EHA disconnected, then look first for a problem unrelated to the O2 sensor and other loop components.
