I got my suv service at a local sears. I got a coolant flush, front and rear differential, an oil change and 4 new tires. 13 days later I started my suv and the engine would only sputter and idle very roughly. A day later I had it towed to a mechanic and he saw that one of the pistons had smashed the spark plug in the #1 bay. I want to know if something they did could have caused this to happen? The engine only has 83000 miles and it is a 4.0 ltr v6 2005 ford explorer 4x4
