February 6, 2005My 2001 F150 just spit out a spark plug. It has about 90,000. Miles on it and was serviced just 3 months ago including new plugs. Anyone else had a problem of popping out plugs? Brewster bb

February 7, 2005Seen it happen on a lot of them with high mileage. After all the heating up and cooling down of the engine, along with numerous spark plug changes, the threads in the aluminum wear out. The best thing to do, would be Heli-Coil it. This way the threads will be stainless and you'll never have the problem again .....
