That would cause a power loss/velocity change on that cylinder, setting the premise for the missfire counter to set a code.

I'd bet money thats the problem. The engine has well over 200K.
It runs pretty good for having such low compression on TWO cylinders.
Maybe thats because it weighs as much as one of my wheels on my silverado.
Thanks for the insight.
