Failed Oxygen Sensor or ECU? 200 80

posted by  someone claiming to be Dave Barton on  Sun Nov 12 05:51 CST 2000 [RELATED]

I'm fixing up an '80 242 DL and I do not know the cars history. I have found that the oxygen sensor, when hooked up, is not properly cycling and the car is basically running rich (I think). I believe the sensor works OK since it produces varied voltage (between 0 and 1 volt) when unhooked from the ECU. I tried another used sensor and it too varies in voltage, but does not cycle when plugged in. I am thinking that the ECU needs to be replaced, but before I buy another one from a salvage yard, I thought I would seek out any of you who have come across this before. Thanks
