Petboys review: Sparkplug

I drove my car to pep boys, because my car suddenly cut off, to make a long story short, after they replaced a spark-plug, they charged me $900. $900 for a spark plug! a day later my car cut off again. same issue. they really did not fix the problem, they just replaced my spark plug and charged me $900. I am not happy with the repair service. I would recommend not taking your car to this establishment.
