2004 Lexus ES Fuel System Problems

ON A FRIDAY MORNING IN OCTOBER OF 2014, I DROVE FROM DC TO BALTIMORE.THE TOTAL DRIVING TIME WAS CLOSER TO NINETY MINUTES THAN THE USUAL HOUR, THE SIGNIFICANCE OF THIS WILL BECOME CLEAR LATER IN THIS MESSAGE. TEN MILES OUTSIDE OF BALTIMORE, I DID NOT FEEL WELL. EVENTUALLY PULLING INTO MY DAUGHTER'S DRIVEWAY, AND FEELING VERY FAINT, I MANAGED TO CALL MY HER VIA CELLPHONE, RIGHT OUTSIDE HER KITCHEN WINDOW. I WAS SO SICK THAT I COULD NOT GET OUT OF THE CAR. I FELT UTTERLY LIMP, DIZZY AND NAUSEOUS AS MY SON-IN-LAW PULLED ME OUT TO STAGGER IN THE FRONT DOOR AND COLLAPSE ON THE LIVING ROOM COUCH. THE ROOM WAS SPINNING; IF I OPENED MY EYES, THE ROOM TILTED AND SPUN FASTER. MY KIDS CALLED AN AMBULANCE. MY VITAL SIGNS - OXYGEN AND BLOOD PRESSURE READINGS WERE WITHIN THE LOW RANGE OF NORMAL, WITH OXYGEN AND BLOOD PRESSURE READING VERY LOW. I HAVE NO RELEVANT HEALTH CONDITIONS. THE AMULANCE ATTENDENTS THOUGHT IT WAS "THE FLU". EIGHT OR NINE HOURS LATER, I MANAGED TO GET UP. IN A FEW DAYS I WAS BACK TO NORMAL AND FELT FINE. LAST TUESDAY, JANUARY 19, IT HAPPENED AGAIN. THIS TIME IT TOOK ABOUT FIVE HOURS TO RECOVER. THE DRIVE HAD BEEN JUST UNDER AN HOUR. I WAS SURE, AT THIS POINT: IT HAS TO BE THE CAR. IT WAS. NEXT DAY I WENT TO THE MECHANIC, THOUGH HE WAS ENTIRELY DUBIOUS ABOUT MY CONVICTION: CARBON MONOXIDE. A FEW HOURS LATER, HE CALLED TO VERIFY THAT THE ENTIRE EXHAUST SYSTEM, ENGINE-TO-TAILPIPE, WAS CORRODED AND THAT, INDEED, CARBON MONOXIDE HAD BEEN LEAKING INTO THE CAR. IT IS AN OLD CAR BY US STANDARDS - A 2004. IT WAS A $2,000 REPAIR JOB - A JOLT, BUT I FELT LUCKY. WOULD A SMALLER PERSON - A TEEN OR PETITE WOMAN, HAVE SURVIVED? WOULD THE CAUSE OF DEATH EVEN BE DISCERNIBLE? HOW MANY DEATHS HAVE WE HEARD OF: "ASLEEP AT THE WHEEL"? PUSH FOR LEGISLATION TO REQUIRE CARBON MONOXIDE SENSORS IN CARS! *TR
