MISFIRING ENGINE

2001 Ford F-150 • 99,000 miles

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?

It's probably unrelated unless it 's the same plug
