I see that it means Mass Air Flow (MAF) Sensor - signal voltage or frequency is high during engine idle. Does that mean I am running to rich? I kinda have a little choppiness to the idle when the car first starts up on a cold start in the morning. Just want to get a little more in depth info on this. Thanks people.
