Frends i want to thank you for yhe help.I resolve the problem.
There was,somehow,pure oil,i mean clear color,in the connector of the o2 sensor.
This sensor is the one with the long cable(BANK1/SENSOR 2).
As an information,i can tell you that there are totally 3 o2 sensors on 1.6 120hp 147
One is the sensor mentioned above,the co-driver sensor is BANK 1/ SENSOR 1 and
the drivers side sensor is BANK 2/SENSOR 1.
I still looking for the electrical drawings of my baby,and the sensors location map.
If anybody has any information,i will like to share it with me.
Thanks a lot
