2001 V6 FORD MUSTANG SUDDENLY STARTED TO MISS-FIRE. I HAVE BEEN SMELLING EXHAUST ODORS FOR SOME TIME, BUT COULD NOT FIND ANYTHING WRONG. I TOOK IT TO THE DEALER AS SOON AS IT STARTED TO MISS-FIRE. THEY DIAGNOSED THE PROBLEM AS A SENSOR WITH MOISTURE IN IT AND BOTH EXHAUST MANIFOLDS WERE CRACKED. IT'S NO WONDER I WAS SMELLING EXHAUST FUMES. I WAS LUCKY NOT TO BE OVERCOME WITH CARBON MONOXIDE WHILE DRIVING. THERE WAS NO APPARENT REASON FOR THE EXHAUST MANIFOLD FAILURE. THE DEALERS REP SAID: " WE HAVE REPLACED QUITE A FEW OF THEM AND THE NEW ONES ARE BETTER". *TR

I STARTED MY CAR AND PUT IT IN DRIVE AND BEGAN TO ACCELERATE WHEN THE ENGINE RACED TO 6000 RPMS. PUT MY FOOT ON THE BRAKE AND THE CAR KEPT ACCELERATING. I PULLED MY PARKING BRAKE AND GOT THE SAME RESULT. I THEN PUT MY CAR IN PARK AND AT THAT TIME I WAS DOING ABOUT 60 IN A NEIGHBORHOOD HEADING STRAIGHT FOR A LIGHT POLE. I JUST BARELY MISSED THE POLE BUT STILL HIT THE CURB AND TOTALED MY CAR. AFTER TURNING THE KEY THE ENGINE STOPPED. A MECHANIC AT THE COLLISION CENTER LOOKED AT MY ENGINE AND SAW THAT MY THROTTLE WAS STUCK WIDE OPEN. THE CAR IS STILL SITTING AT THE COLLISION CENTER WAITING FOR A FORD REPRESENTATIVE TO COME AND LOOK AT IT. *TR

THERE IS A RATTLING, BANGING NOISE COMING FROM UNDER THE HOOD. IT ONLY DID IT AT FIRST WHEN I WAS SLOWING DOWN WITH AND WITHOUT THE BRAKES. IT SOUNDS AS THOUGH THE CAR IS FALLING APART. I TOOK IT TO FORD AND THEY TOLD ME THEY HEARD THE NOISE BUT IT WAS NOTHING MECHANICAL AND THEY DIDN'T KNOW WHAT IT WAS COMING FROM. THEY TOLD ME THEY CHECKED ALL OF THE PARTS UNDER WARRANTY AND IT WASN'T THAT. THEY TOLD ME THAT IF I WANTED THEM TO CONTINUE TO LOOK FOR THE PROBLEM, THEY WOULD HAVE TO CHARGE ME BY THE HOUR. THE CAR STARTED MAKING THE NOISE ABOUT 6 MONTHS AGO. IT WILL GO AWAY FOR A FEW DAYS AND THEN COME BACK WORSE. NOW IT DOES IT WHEN THE CAR IS STOPPED ALSO. NO ONE CAN FIND THE PROBLEM.*JB
