2002 FORD F SERIES (LIGHT) Engine Problems

WE PURCHASED A CAR FROM NAB AUTOS IN FREDERICKSBURG, VA. AFTER THE 7TH DAY OF DRIVING IT, THE MOTOR BLEW UP. WRONG SPARK PLUGS WERE INSTALLED BY DEALER. ALSO THE TRUCK HAD BEEN RACED WITH NITROUS WHICH WE WERE UNAWARE OF UNTIL WE TRIED TO FIND OUT WHAT HAPPENED TO MOTOR. I HAVE DOCUMENTATION FROM THE REPAIR SHOP. MY 18 YEAR OLD SON DRIVES THIS VEHICLE WHICH BEGAN LOSING POWER AND SHAKING BEFORE HE WAS ABLE TO PULL OFF TO THE SIDE OF THE HIGHWAY.

SPARK PLUG FAILURE AS ACCELERATING FROM A STOP LIGHT, AND ENGINE PROBLEM RESULTING FROM 7 CYLINDER OPERATION. GOT IT TO A MECHANIC AND HE WAS ABLE TO SLEEVE THE SPARK PLUG THREAD AND INSTALL A NEW PLUG. NOW THE SAME IS STARTING AGAIN. I AM TAKING THE VEHICLE TO THE MECHANIC TO MAKE PERMANENT REPAIRS FOR ALL THE SPARK PLUG. THIS MAY END UP WITH THE ENGINE HEADS BEING REMOVED IN ORDER TO MAKE COMPLETE REPAIRS, AND THE COST FOR THAT WILL BE THOUSANDS OF DOLLARS. THIS IS A FORD ENGINE DESIGN PROBLEM THAT FORD HAS BEEN AWARE OF, YET THEY CONTINUE TO DENY ANY RESPONSIBILITY. *TR

OIL LEAKING PASSENGER SIDE REAR ON TO THE STARTER AND EXHAUST SYSTEM. *TR

A SPARK PLUG WORKED LOOSE FROM THE HEAD AND BLEW OUT CAUSING DAMAGE TO THE HEAD AND THE IGNITION COIL. ALL 8 PLUGS HAD TO BE REPLACED, TWO DAMAGED SPARK PLUG HOLES REPAIRED AND TWO IGNITION COILS REPLACED. *TR
