Bit confused on what you want, but happy to play!

I can hook up VCDS this afternoon and look the fuel trims, LPG or Petrol?

CO is fine on LPG, though HC is high, but just within the *MUCH* wider limits than on petrol and only until the LPG drops cylinder 8 though it also mentions 10??? It's only a V8

I think what is happening is that the post cat sensors being out is meaning that it's either under or over fueling causing the emissions issues and the LPG is trying to trim to such an extent the miss fires are happening!
