CARBON MONOXIDE SEEPS INTO THE PASSENGER CAR BUT DILLER CANNOT FIND IT AND DID NOT HAVE TOOLS TO DETECT CO LEVEL IN THE CAR. I CAN'T USE THIS CAR BECAUSE WAS POISONED MANY TIMES AND AFTER A SECOND CHECK-UP, THE LEVEL OF CO BECOMES HIGHER SO I CAN'T DRIVE THE CAR WITHOUT POISONING. PLEASE HELP ME. I AM WORRYING TO SELL MY CAR BECAUSE OTHER DRIVER WILL GET INJURY. THIS IS THE NEW CAR ONLY 7000 MILES.
