TO WHOM IT MAY CONCERN:I HAVE TAKEN MY 2002 OLDSMOBILE INTRIGUE 3.5 BACK TO THE DEALER 3 TIMES COMPLAINING OF EXHAUST FUMES GETTING INTO THE PASSENGER COMPARTMENT AND OLDSMOBILE SERVICE KEEPS SAYING THAT THEY DO NOT SEE OR SMELL ANYTHING WRONG. THEY ALSO SAY THAT THE OBD 11 ON BOARD DIAGNOSTICS WOULD TURN THE CHECK ENGINE LIGHT ON IF SOMETHING WAS WRONG. I HAVE USED A DIGITAL HOME CARBON MONOXIDE TESTER IN THE PASSENGER COMPARTMENT AND IT HAS REGISTERED FROM 7 PPM TO 27 PPM. I DRIVE TO WORK MONDAY THRU FRIDAY FOR ONE HALF HOUR, SEVENTEEN MILES EACH WAY. WHEN I ARRIVE MY ARMS HAVE A PURPLE COLOR. MY VOICE HAS BECOME WEAK. I AM SLURRING MY WORDS. I OPEN THE CAR WINDOWS NO MATTER HOW COLD IN AN EFFORT TO GET FRESH AIR. MY BEHAVIOR HAS BECOME ERRATIC. ON THE WEEKEND I STAY AT HOME TO TIRED TO GET UP AND GO OUT. ON SUNDAY NIGHT I START TO FEEL MY ENERGY RETURN TO THE POINT THAT I FEEL LIKE EXERCISING. MONDAY MORNING I GET UP DREADING THE THOUGHT OF HAVING TO DRIVE TO WORK BECAUSE THE CYCLE WILL START ALL OVER AGAIN. I HAVE GONE AWAY ON VACATION AND USED A RENTAL CAR AND MY ENERGY STARTS TO RETURN. MY OPINION IS THAT MY GM CAR IS CAUSING THESE PROBLEMS. THERE IS A PERSON ON THE WEB WHO IS EXPERIENCING THE SAME PROBLEMS I AM. HTTP://WWW.COHEADQUARTERS.COM/COMOTOVEH/COMOTOVEH1.HTM ONE COLD AND RAINY DAY I HAD TO DRIVE ONE HALF HOUR AT HIGHWAY SPEEDS WITH THE WINDOWS UP. WHEN I ARRIVED AT MY DESTINATION I WAS IN A DIZZY STATE OF MIND AND BACKED INTO A LIGHT POLE CAUSIN
