We just replaced a spark plug and coil in our truck last Friday because it blew out and the ford mechanic said I was probably due to a defect in the engine. Looking into it further, I soon realized it is a common problem. Now the truck is misfiring, but the engine light is not coming on. I was just wondering are the other spark plugs going or is it something completely unrelated?
have the same problem?
