P38A Fuelling

1995 4.6 Auto
Just had dashboard out to replace heater as wasn't just O rings leaking.
Now she is "hunting" so put nanocom on and bank 2 lambda sensor isn't working and No 2 injector short or ground fault
Is there anything obvious I have done wrong?
From driving seat, is No 2 the furthest away on left?
And is the left hand bank bank 2?

Cylinders numbers are:

AS SITTING IN THE DRIVER SEAT:

LH RH
1 2
3 4
5 6
7 8

LH is Bank 1
RH is Bank 2

Don't know about you but we had a bugger of a time getting the new (rubber) heater pipes through the bulkhead without pulling the grommet through. Or did you put the old ally ones back in? Could well have knocked something I was thinking.

Yes it was a bugger so I will look there ta
Got rid of ally pies and "O" rings

Fixed injector and now both lambda sensors say "cl use o2" so guess they fixed too ta.
BUT on nanocom long time fuel trims are approx -145 and short term approx 6.
What do they mean?
Nano also has a button the reset adaptive values.
What is that?
I can gap points and plugs etc with feeler gauges and tune a carburettor by ear but electronic stuff is beyond me I am afraid

I replaced the exhaust with a Janspeed stainless one. Could that affect fuelling etc?
