Thought I'd follow up on my last post. This problem seems to have fixed itself. I now think I filled up with a load or two of crappy gas. I do now notice some very minor pinging but I would think our local fuel suppliers are still pumping the lower BTU winter grade fuels.

Thanks for those who tried to help.
