NHTSA Complaint #10303318 — 1997 FORD F-150

I WAS DRIVING MY TRUCK AND HEARD A LOUD POP, AS IF A TIRE HAD BLOWN OR DRIVE COMPONENT BROKE. MY TRUCK BEGAN TO RUN ROUGH AND SHAKE AFTER THE NOISE AND CONTINUED WHEN I CAME TO A STOP VERY SHORTLY AFTER THE SOUND. IT ALSO CONTINUED AFTER I CAME TO A STOP AND PUT MY TRUCK IN PARK. ALSO, IT INCREASED IN SEVERITY BUT LESSENED IN TIME INTERVAL, OF AN OBVIOUS KNOCK. I LEARNED I HAD BLOWN A SPARK PLUG OUT OF MY HEAD, TAKING THE THREADS IN THE HEAD WITH IT. THE TWO OPTIONS ARE TO REMOVE THE HEAD FROM THE MOTOR, WHICH COSTS ABOUT WHAT THE TRUCK IS WORTH, OR TO FIX IT WITH THE HEAD ON THE MOTOR AND TAKE CHANCES THAT NO METAL SHAVINGS ENTER THE CYLINDERS. BOTH OPTIONS REQUIRE A HELI-COIL FOR THE HEAD. I HAD TO HELI-COIL MY HEAD TO REPLACE THE SPARK PLUG SINCE THERE WERE NO THREADS FOR THE SPARK PLUG TO ATTACH TO. *TR
