Hi my name is ***** ***** am here to assist you Today i take it he has tested the post catalytic lambda sensor.
It should have two for a closed loop lambda.
He must of tested it is he looking for a wiring fault now.
Yes check the live data out.
Not sure about the injector theory.
I have it down as post cat sensor.
The code is not a pin point it never is it is just a guide the rest is down to testing.
Trouble is we do not know how he is doing the testing they are not to bad to check with the correct equipment i think you need to get it tested at a different workshop.
That is the problem he is just going of the code without testing it is called bolt on diagnostics and it is an expensive habit.
You are not falling out with them you are just getting this issue checked out somewhere else that code points more to the post cat sensor.
No problem regards Gavin.
