I'm a bit confused. Is the plug in there now and presumed stuck and cross threaded? Did a plug break right off leaving threads in the original hole or just what has happened??

Reply to Tom Greenleaf: The plug is still in there. I took it in to get spark plugs put in. The mechanic says that he couldn't get the number 4 spark plug out, because the bolt was cross threaded. It wasn't missing that day, but he said that it might start misfiring. After about a week my truck starting missing pretty bad, and then my engine light came on. I took it to the mechanic to check it out and diagnosis was #4 plug misfiring. The mechanic said this would be a costly repair, because the plug would have to be taken out at the head.

Is it the spark plug that is cross threaded, or the little bolt that holds the coil in place? I do not think the spark plug has been cross threaded. It may be rusted in place and hard to remove. A competent technician should be able to remove it using a little time and lubricants they have available.

If it is the bolt that holds the coil, it can be removed and a self tapping bolt installed. Not a big thing. It is done quite often. Good luck.
