I have a 1997 Ford exp with a 5. 4 engine, I was driving along and I heard this loud pop sound and then lost power! I open the hood and found that the spark plug ejected out the engine and blew the ign coil apart. I have had three set of spark plugs installed from 1998-2007 and never had a problem(175896 miles on my truck). Im a auto tech by trade and have worked for western auto for 11years, and pep boys auto for 14 years. Over the last several years I have seen alot of Fords trucks come in with this problem ! with so many people having the same problem when will Ford be held accountable or some type of recall put in place ?it has not been fix yet , but I have look into buying a online insert kit that drills out the spark plug hole and install new threads to repair the damage threads. The cost of the kit is $367. 95 and im doing the work myself but im sure it would be between 900 to 3000 thousand dollar if I have gone to a shop for repairs. Please contact me with a response ? thank you for your time!.
Was driving home from work, heard a loud noise and truck got really loud. Got it home checked it out. The spark plug blew out. Had to take it to a dealer and get a new insert put in cause it was stripped.
Spark plug blew out of cylinder #6 while traveling at highway speed. This resulted in a loud noise and a check engine light, strong smell of gasoline. Due to outside temperatures of -10 deg f car was driven to nearest exit, lucky there was no fire.
