Took my car for a service, two weeks later my spark plug shoots out, and it is obvious to see that it is not a new spark plug. then i get told that the spark plug that came out is not the ones they use, but all four spark plugs are the same make and brand. they also told me that the spark plug that fell out must have been lying in the engine for a year, and fell out when the "new" spark plug fell out! i haven't found the "new" spark plug any where on the ground in my drive way. amazing how people think that they can BS you because you are a woman!
