The timing of the injectors, valves etc. Normally the car will detect small changes and adjust the ignition timing for them.
Sorry, but I don't know enough about the 2.2 engine to be much more help.
Use the search function on the site (not just the 159 section, as the engine is used in many models), as there are a few threads, some mention checking the MAF too, so might be worth disconnection it and seeing if it helps. That would be a very easy check to do, as it seems to relate to a couple of the error codes.
