]Hi threedogs not yet I think I will but am wanting it sorted or at least the sensors replaced to eliminate them fairly soon.
I have been out playing with it again and /#€k me it looks like the sensors have been plugged in backwards found a post on another forum stating that the rear sensor bank 2 should be the wiring loom with a green and yellow stripe and the front the loom with blue and red stripe and mine were the other way around. Sensors are now showing some erratic measurements on petrol but still shows constant voltage on bank 2 so that sensor must be dud. Strange as swapping them over appears to have fixed this lagg/stumbling/surging issue when on petrol (only drove around the block).
Can anyone confirm the colour coding on the engine side of the wiring looms to the first and rear sensor ?
Have the battery disconnected at the moment will connect it back all up in a bit and have a look at the readings and go for a drive.
