My engine will sometime stall while I am driving thus no foot brakes and power steering. It usually stall when I am slowing down or just pick off. Have it checked with few workshops and even authorized workshop of Nissan but they can diagnose any faulty codes.I have changed fuel pump, ignition coils, spark plugs, throttle sensors, temp sensor and yet can't find the exact fault which is real demoralizing.I will be changing timing sensors soon to check. Please help.I really need help. Thanks

You would be changing the engine soon if you continue thus.

Have you checked for trouble codes?

Symptom indicates an idle control fault, was the throttle body and IAC cleaned?

Thanks low, I have changed my engine few months back due to overhaul. The throttle has been cleaned as well. The tricky part is that the car can stall without any signal or jerking.I always suspect it has to do with those sensors or electronic parts. Any advise beside IAC?

The IAC is the main controlling component for idling and when no trouble codes are present, it can mean the IAC is sticking intermittently. When IAC don't work well, turning the A/C on and off would make the idling speed unstable, at least momentarily. Try that to see if it makes any difference.

When it stalled, was it easy to restart?
