Spark plug blew out stripping threads.
I am one of the thousands of Ford owners who have had spark plugs blown out of the cylinder heads while driving. This is a major disgrace that you all will continue to let fmc lie and steel from its customers and deny that there is a problem with there engines. Please do the right thing and make Ford stand up for their mistakes.
