BLOWN FORD SPARK PLUG! I DRIVE A 2001 FORD MUSTANG GT, 4.6L V8, AND ONE NIGHT I WAS SITTING AT A RED LIGHT AND AS SOON AS IT TURNED GREEN I STEPPED ON THE GAS LIKE ANY OTHER LIGHT AND I BLEW A SPARK PLUG. I BOUGHT THE CAR USED WITH 10K ON IT AND IT BLEW AT 56K. I NEVER REPLACED THE PLUGS SO IM GUESSING THEY WERE FACTORY INSTALLED. AS OF TODAY I HAVE REPLACED BOTH HEADS BUT THE DAMAGE FROM THE BLOWN SPARK PLUG SEEMS TO HAVE AFFECTED MY ENGINE BLOCK ITSELF. MY GUESS IS FROM DRIVING THE CAR OFF THE ROAD INTO A PARKING LOT. NOT HAVING MONEY TO REBUILD THE ENGINE I HAVE SINCE PARKED THE CAR HOPING FORD TAKE RESPONSIBILITY FOR ITS MISTAKE. I HAVE READ MORE AND MORE HOW MANY FORD V8S TEND TO DO THIS YET FORD ACTS LIKE IT DOESN'T EXIST. I CALLED FORD ABOUT ORDERING NEW HEADS AND THEY INSISTED THERE IS NO PROBLEM. I WAS RAISED ON FORDS BUT DON'T SEE ME BUYING ONE EVER AGAIN. *TR

2 WEEKS AFTER I BOUGHT THE CAR, I HAD REPORTED PROBLEMS WITH ENGINE AND TRANS AND REAR-END. THEY KNEW ABOUT IT, BUT SAID THEY DID NOT HAVE THE KNOWLEDGE TO WORK ON A SELEEN, WHICH THAT IS WHAT I WAS TOLD I WAS BUYING AT THE TIME. COME TO FIND OUT IT IS NO. BIG DIFFERENCE IN PRICE. ON OR ABOUT FEB 15TH 2006 THE ENGINE BLEW, I HAD PARKED IT IN THEIR PARKING LOT. THEY HAD MY CAR FOR A TOTAL OF 45 DAYS. STILL NO TRANS WORK OR REAR-END, THEY SAID TO BRING IT BACK IN 30 DAYS. ADDING ON THE LINKAGE WAS DAMAGED WHEN THEY HAD IT. I HAD TO PAY OTHER SHOP TO FIX. ALONG WITH ENGINE PROBLEMS, ENGINE LIGHT WAS ON. SINCE JUNE OF 2006 MY CAR HAS BEEN IN THE SHOP 10 TIMES , TOTALING 55 MORE DAYS. RENTAL CAR COST OVER 2500.00 AND TIME AND MENTAL ANGUISH . LUZZI REFUSED ME THE 2ND TIME ENGINE BLEW BECAUSE THE FACT I AM MARRIED TO DAVID HARDING. HE IS NOT ON ANY CONTRACT WITH ME. THEY REFUSE TO DO ANY WARRANTY WORK ON THE ENGINE THEY INSTALLED 9 MONTHS AGO. I PAID FOR A WARRANTY WITH THEM FOR 1800.00 AND I WAS CANCELLED BECAUSE OF THE MONEY ALREADY PAID FOR THE CAR. 10 MONTHS , WHERE'S THE OTHER 2 YEAR PRORATED FEES? THE LIST GOES ON AND ON. *NM

IT WAS STILL UNDER THE 30 DAY/3000 MILES USED VEHICLE WARRANTY AND IT WAS FIXED AT NO CHARGE TO MYSELF. THE SAME THING HAPPENED AGAIN A WEEK LATER AND I WAS TOLD (IN THE BEST WORDS THAT I CAN DESCRIBE IT) THE THREADING IN THE HOLE OF THE PART OF THE ENGINE THAT THE SPARK PLUG SCREWS INTO, WOULD NO LONGER HOLD THE SPARK PLUG AND THAT THE ENGINE NEEDED TO BE SENT TO A MACHINE SHOP TO BORE THE HOLE IN DEEPER COSTING A AROUND $3000.00. *NM

WHEN HE CHECKED THE CAR, HE FOUND OUT THAT THE SPARK PLUG WAS LOOSE, HE JUST PUT BACK. A COUPLE OF MONTHS LATER, I HEARD THE NOISE IN THE ENGINE AGAIN, I KNEW WHAT THE POBLEM WAS SO I PUT THE PLUG BACK IN. SOME MONTHS LATER (12/04) I HAD THE SAME PROBLEM, BUT THIS TIME THE PLUG WOULDN'T TIGHTEN, SO I CALLED MY MECHANIC AGAIN. HE CHECKED THE CAR AND FOUND OUT THAT THE THREAD IN THE SPARK PLUG HOLE HAD STRIPPED. I BOUGHT A SPARK PLUG THREAD KIT AND HE WAS ABLE TO FIX THE ENGINE, BUT THE ENGINE DIDN'T PERFORM THE SAME. *NM
