I might be interpreting your description of the symptoms incorrectly. If it never stalls while driving, it's not a sensor problem. The fuel spray that you saw stopping might be the result of the stalling, and is not the cause of it. Since this only happens at idle, it's more likely it's being caused by a very common problem. If the battery was recently disconnected or run dead, the Engine Computer lost its memory and has to relearn "minimum throttle" before it will know when it has to be in control of idle speed. Until that relearn takes place, the engine can be hard to start unless you hold the accelerator pedal down 1/4", you won't get the nice "idle flare-up" to 1500 rpm at engine start-up, and it will tend to stall at stop signs.
To meet the conditions for the relearn to take place, drive at highway speed with the engine warmed up, then coast for at least seven seconds without touching the pedals.
