    By now there is likely a check engine light on or it was on right? You need to access the fault codes stored in the computer memory to assist in diagnosing this problem. Separately, there is a possibility of a bad MAP sensor. I see multiple confirmed fixes for stalling and the fix was the MAP sensor. Follow the codes first.
