Hi All

Apologies, I know this thread is similar to others, but I think my issue is caused by something not addressed on the forum (by all means correct me if im wrong)

My L322 is lumpy at idle on bank 1, under load, and driving at constant speed. Live data shows an imbalance in Air mass readings. Bank 1 is 10x what bank 2 is.
HOWEVER on a hot day, both read the same and the car runs perfectly. It seems the high airmass reading is causing an injector offset, hence the lumpyness and smoke.

Error codes:

* Injector offset
* Air mass reading out of scope

No other codes

Here is what we have done:

* Smoke test came back okay
* Air mass meters swapped round AND replaced on bank 1
* EGR replaced twice on bank 1
* Replaced ALL injectors on bank 1

Any help would be appreciated as im really at my whits end with it.

Thanks

Nick
