It should go into "fault" mode and run off pre-loaded fueling tables. Depending on the temperature/climate vs those tables, it SHOULD run fairly well. Not great...just OK.
FWIW, the car is drivable w/o the MAF too.

I had disconnected my MAF during a troubleshooting session and forgot to plug it back in. I drove the car to work the next day and couldn't tell it was unplugged.
Unplugging the MAF will NOT put the ECM into LIMP mode. It knows there is a problem and uses the TPS position to guess what the airflow is. It will set an error code.
