When trying to start, the van will start, then shut off, unless you tap the accelerator while starting. Sometimes the starter will actually hang up and continue turning over after the van is already running. I have tried to clean the mass airflow sensor, but am not sure how to remove it from the housing. Any help or suggestions will be greatly appreciated.
