That is very helpful and I am starting to understand.
However, Things have changed!
I now have both Fuel Sys 1 and 2 showing OL (open loop i believe).
STFT and LTFT all read 0% and do not change with load.
O2 sensors (pre-cat, my car does not have post cat) read 0.435v and do not change with load.
No fault codes are showing.
It was suggested to me that the car is now running on its basic mapping without any input from sensors. I have disconnected that battery for 24 hours to see it anything re-sets but without any result.
Any suggestions?
