Ignition Coils for 2012 F150 eco boost
My 2012 F150 (only 87000) miles just went to shop. Knock under load turned into engine light coming on while on expressway 400 miles from home. $870 repair! 3 ignition coils and on other side 3 boots. All new spark plugs. Not happy. Had spark plug issues on last F150 (2008) and ate that repair too. Ford claims they are not familiar with ongoing problem...after Ford tech told me that it happens all the time.
