k, i know this is a "heated oxygen" sensor code. i did search too.
-i have 97 B20 in my 92 VX hatch. 92 teggy ecu. 4 wire o2 sensor that was running perfectly in the old civic engine. the sensor itself looks pretty new. maybe was replaced before i bought the car.
-problems are: searches for idle (checked all my vacuum lines), studders slightly at lower rpm. and...duh, CEL light is constantly on.
-do i have the incorrect ECU/o2 sensor combination?, or do you think the 02 sensor itself went bad??

thanks people,
