What can it be? So weird, it happened twice today, w/o any sign. Last she did this was back in 2011, when the Camshaft Position Sensor went wrong. Since I replaced the sensor the problem was gone, never came back.

It only happens at very low speed, i.e. come to a stop-sign, or a stop light. Usually it comes after a sharp steering (or during steering), which is very dangerous. Please advice, guys! Need your inputs! Fuel Pump aging?

BTW, no check engine light.

Thanks!
