If larger injectors have been installed and a chip tuned for those injectors has not also been installed, the engine could be running rich. A bad thermostat that is causing the engine to run cold or a bad temperature sensor making the DME think that the engine is running cold could also cause a rich condition.

Also look at the black lid on the airflow meter, if it appears to have been removed someone may have messed with the spring inside, this will absolutely cause a rich condition.
