Original factory spark plug backed out from cylinder head. Checked remaining 7 spark plugs. Four of seven loose. Mechanic recommended using heli coil kit on all spark plug threads. Mechanic mentioned that this was a common occurrence on Ford 5. 4 liter engines. If this is true, it appears as though a recall should be required for repair of cylinder heads.
Car keeps dies in traffic almost everyday and the electronic throttle control light keeps coming on . Ford wants $800 to fix. With this safety issue, I believe there should some sort of action Ford should take and fix the problem since it is always happening to this year and model so often.
