**** UPDATE **** Been back to work and got the fail. I know you will want 4 gas readings idle and fast idle but this is what I have now.... IDLE FI 1 FI2
I'll try and nip back to work and get the fail sheet and I'll do another one on Monday, but they are all over the place dont think they I have had the same reading twice. But you are right vital for diagnosis.
To be honest I haven't used the sensor earth and signal at the same time. If I use the sensor earth and it starts switching the same as live data it will prove it's a floating earth. The floating earth idea only came to me on the way home today and I've not had any time to prove it.
It looks an after market cat by the size of it, its probably half the size of the original one I'm guessing.
Sorry I forgot to say before I havn't checked LTFT and STFT this would help prove the vehicle is in control of fuel wouldn't it, then and prove it is more a cat issue rather than fuel issue.
Many Thanks
Andrew

Can i just add that the tester held it close on flat out for 5mins before getting this resault. He had the idea that if he got the cat RED HOT it would work
