Default ya so my engine shut off by itself....

i was just driving and when i pushed in the clutch to go to neutral and coast , it died. i was thinkin in my head that maybe when the throttle body blade closed , maybe this particular time pushed the air back far enough from the previous vacuum that it swept my maf and threw a bad reading that my car didn't like. thats just conjecture tho. any similar issues with anyone else? only happened 2 times in 1 year.

+1 on the IAC, try cleaning it with carb cleaner if you can't replace it right now
