Question about 1994 Volvo 940
SOURCE: engine stalls out when put
If the mass airflow sensor is unplugged the on board computer can't read the air flow to the fuel system, hence the dying. Their is a cheap remedy that may work, you can purchase a MAS sensor cleaner and after you pull the sensor simply spray it liberally and it may work again. If this doesn't help you will need to replace the MAS sensor for the vehicle to run correctly.
