That was determined to be a plug gone bad. I can almost
understand the plug thing if it wasn't for the fact that I have had
other engines with normal plugs, and I change them out of routine
maintenance, and not too frequently.

The Lincoln Navigator tow vehicle got the recommended new plugs at 100
000 mi, although they looked fine. On the Navigator, it takes about
two hours to change the plugs, so it is just as well they last so
long. Platinum points. You can't get such a thing for your engine.?
