Reply To: GT250 EFI 2012 Issues arising from Issues
It sounds silly, what if you bought all new sensor ? and see if the problem continues?
Also, check manualsLIB online for your 2012 model to get a service manual, there is a page that allows you to check if the connector near the ECU is breaking up signals ?
I know the 2012 is a DAEWOO with a very large single plug , the 2009-2012 really do have sensetive ECU connector plugs. It is perharps the ECU fault or the ECU itself is not able to reliable read the harness leading to the sensor.
You can test for example = Purple wire (example) from the O2 sensor connector and test the same color near the ECU plug , to see if the circuit is broken using a multi meter or if it is acting haywire if you move the harness around (incase of kinks)
