That is the, "Air Flow Sensor".
You might try disconnecting the negative battery cable for 30 seconds. This will reset the ECU. If it happens again you might have to have the Air Flow Sensor replaced. Before you do that, do some further diagnostics.
The best thing to do is go to an Advance Auto or Auto Zone and they will read trouble codes for free. Then come back to us with the trouble codes.
