I EXPERIENCED AN INCIDENT BEFORE THAT MY CAR STALLED BUT IT RESTARTED QUICKLY. THEN FEW WEEKS LATER MY CAR STALLED AGAIN BUT THIS TIME DID NOT WANT TO START UP AS QUICKLY AS BEFORE AND MY CHECK ENGINE SOON LIGHT CAME ON THIS TIME. AS SOON AS IT STARTED UP AGAIN I WENT STRAIGHT TO THE DEALERSHIP WHERE I BOUGHT THE CAR. ON MY WAY OVER THERE I WAS DRIVING ON THE FREEWAY AND I FELT MY CAR LOOSING POWER AND IT JERKED BACK. I WAS VERY AFRAID THAT MY CAR WOULD STALL OUT WHILE I WAS DRIVING ON THE FREEWAY. I WENT TO THE DEALERSHIP AND EXPLAIN MY SITUATION BUT THEY WERE NOT ABLE TO HELP AT THAT TIME BECAUSE THEY WERE BOOKED UP. I LEFT AND WENT TO AUTO ZONE AND THEY PERFORMED A DIAGNOSTIC TEST ON MY CAR. THE REASON MY CHECK ENGINE LIGHT CAME ON WAS DUE TO MALFUNCTION OF THE CRANKSHAFT POSITION SENSOR ON MY 2005 NISSAN ALTIMA. NEXT MORNING I WENT BACK TO THE DEALERSHIP AND THEY PERFORMED A DIAGNOSTIC TEST TOO AND CONCLUDED THE SAME THING. THEY REPLACED IT WITH A NEW CRANKSHAFT POSITION SENSOR. THE CHECK ENGINE LIGHT IS OFF AND THE CAR RUNS SMOOTHER AND HAS NOT YET STALLED OUT. *TR
