The Mass Airflow sensor is most likely the cause of your issues. If the sensor fails to give the computer accurate readings, the engine will have a misfire. This is likely the cause of the second code you are receiving. You may want to start by removing the sensor and cleaning it. The sensor can become dirty and have collect build up which skews the readings it sends to the computer. Clean the unit, reinstall it, clear the troubleshooting codes, and then test drive. If the code sets again, you will need to replace the sensor. For exact instructions for the removal and cleaning of the unit, you will want to look for your SPECIFIC make and model.
