My SUV has been stalling when I start to come to a stop or slow down to make a turn or just randomly when the truck starts idling too low. I was told that I needed to change the mass airflow sensor, but I just changed it and the truck is still doing the same thing as it was before. What could be some other causes of this?

Hello thanks for using 2CarPros.

it seems the idle control valve is the problem or vacuum leak that leans up the mixture and engine stalls.
