I don't have one of those Gary. But I think the timing light should at least give me a clue if one wire is not firing.
It be nice to have a computer that would send codes like we have on our C7's. LOL

I checked the 8 plug wires and they all show they are firing.
I will let it cool down and check the cap to see if I can see anything.

I took a pic of the cap & rotor. A little pitting on the rotor. Not sure it is enough to cause this issue.
