Lambda Sensor issue

Ask Grant67 and see what he comes up with?

I never questioned whether the front and rear were different as I already knew they were or they wouln't have a different plug. At least we can now agree that sensor I have is in fact a front sensor, which I knew all along, how can it not be if it plugs in to front sensor plug and hasn't been tampered with. The site I linked to wasn't where I have bought my sensor, I used it to demonstrate that the part number for mine was actually linked to the part number you posted for the front sensor.

The questioning was because i could not see the last number and you have only just mentioned it!

You`ll be surprised threads i have answered where the plugs have been swopped because of money involved, owners will do anything to avoid paying for genuine parts then complain the engine won`t work properly. As said i pay top money for a top reliable part with no consequences. No, i am not money bags just can`t abide cheaper components on the car which i like and enjoy.

To be quite honest i have given up answering questions about this type of thing, the forum must get bunged right up with these questions as they won`t even do a search?

So do you still have a problem or have you solved it and was just pointing out different motorfactors and prices?

I'm still running lean from idle right through to WOT. Front lambda definitely fubbered as it doesn't deviate from 1V at any point. MAF maybe under reading airflow slighty too from my logs but I'm going to start with the lambda, see what this solves then work from there. New gen TPS. No air leaks anywhere.

Now this is interesting.

I'm still to replace mine with genuine Volvo ones but my forward sensor also stays at a constant 1.000v and doesn't deviate.
My rear sensor does read at a slightly different level of between 0.960v - 1.000v and i don't know if that is the reason why my car seems to act like its suffering from slight fuel starvation as accelerates through the rev range.
It will sometimes do it when i have to slow down and i stay in third gear and accelerate.
Not sure why it is doing this but then i do have to replace my ignition packs and HT leads as the stems are cracked.

I may also have to look at the MAF but will try with the ignition packs and leads first.
