1993 Nissan Sentra Engine

THIS HAS HAPPENED MANY TIMES BEFORE IN THE PAST 3 YEARS THAT I HAVE OWNED THIS CAR. I WILL BE DRIVING AND FOR NO REASON THE CAR CUTS OFF. SOMETIMES I AM DRIVING UPHILL, SOMETIMES ON STRAIGHT, FLAT ROAD. I WAS ALMOST REAR-ENDED YESTERDAY BECAUSE FOR NOW REASON, AND NO WARNING MY CAR STOPS DEAD IN IT'S TRACKS. ALL THE ENGINE FAIL LIGHTS COME ON, AS IF YOU WERE JUST STARTING THE CAR IN THE MORNING. THE CAR HASN'T BEEN DRIVEN FOR AN EXTENDED PERIOD OF TIME, MEANING IT'S NOT OVERHEATED WHEN THIS OCCURS. I HAVE HAD A FUEL INJECTOR REPLACED. TEMPERATURE SENSORS REPLACED MORE THEN ONCE. ALTERNATOR WAS RECENTLY REPLACED AND NUMEROUS BATTERIES. NOTHING CORRECTS THE PROBLEM.

WHEN DRIVING AT ANY SPEED THERE IS A KNOCKING NOISE COMING FROM THE VEHICLE AND THE VEHICLE IS STALLING. DEALER CAN'T DETERMINE THE CAUSE OF THE PROBLEM. *AK

WHEN VEHICLE IS FIRST TURNED ON THE ENGINE STALLS. DRIVER HAS TO KEEP FOOT ON PEDAL AND REV ENGINE TO KEEP IT FROM STALLING. *AK

VEHICLE HAS A HISTORY OF STALLING, BUCKING, HESITATION IN THE ENGINE, A COLLISION RESULTED FROM THIS STALLING PROBLEM.
