Haf my car plugged in a couple days ago and it was showing a faulty pre cat lambda. I expected this as my MPG have been low for a while now which is a why i had it plugged in, in the first place.
Anyway, ive gone from getting 26MPG, to this;
However, walking to my car and i could notice something hanging down, yes you guessed it, the lambda sensor!
But it doesnt look rite to me, is this the rear lambda? Its going from the de-cat then forward. I thought the rear lambda wrnt from the de-cat towards the rear of the car?

Is it the rear sensor simply hanging down? Its the pre-cat sensor that ive had replaced.
