definitely sounds like air leak. It can be intermittent or constant. Remove
every hose from air-flow sensor to the manifold and check for cracks/leaks.
The cracks can be hard to find until you take off the hose and look at the
bottom and under the clamps. My car would die sometimes when coming to a
stop and then stopped running at all when the hose on my turbo cracked. It
had been that way for a while prolly, it just came apart under the clamps
cuz of age and oil. Also check for ignition coil connections. good luck.
