NHTSA Complaint #10151547 — 1999 FORD F SERIES (MEDIUM)

WHILE DRIVING MY 1999 FORD TRITON V-10 POWERED C-CLASS MOTORHOME IN HEAVY TRAFFIC THE ENGINE MADE A LOUD BANG. AFTER THE BANG IT CONTINUED TO RATTLE BADLY AND MIS-FIRE. WORKED MY WAY ACROSS TRAFFIC AND STOPPED IN A NO PARKING ZONE FOR 2 HRS AWAITING A TOW TRUCK. WE WERE IN A FAIRLY UN-SAFE POSITION, AS THE SHOULDER WAS LIMITED AND IT WAS ON THE EXIT ROUTE FOR THE CALIFORNIA SPEEDWAY JUST AFTER A NASCAR RACE. THE REPAIR SHOP HAS TOLD ME THAT A SPARK PLUG BLEW OUT OF THE CYLINDER HEAD. I'M LEARNING THAT THIS IS A COMMON OCCURRENCE ON THIS MODEL ENGINE. *NM
