car cutting off

[LXH89]

If it dies immediately after the first start in the morning then will start and run fine after wards, it may be the Barometric pressure sensor. Another possibility is the Idle Air Bypass valve being clogged and need cleaning. The IAB is a common problem but its symptoms are usually the car not wanting to start with repeated attempts or will not idle without pushing on the gas (also likes to stall with AC/Defrost on).
