The service engine soon light came on. I went to get the code checked and the guy at auto zone said that cylinder four came back as misfiring. He stated that all I needed was a spark plug for cylinder four, is this accurate. And I am not sure where you guys live but there are these fraudulent know it alls that work on cars outside of places like auto zone. The guy said it takes three hours to replace a sparkplug on cylinder four in a ford expedition. And then he said it may not be a spark plug at all, it could be anything. Is the fake know it all right or the person that read the error code. If the error code says that I need a spark plug, is that simply it?
