Bedros,
Thanks for the suggestions, I discovered what had happened. It was the spark plugs. Took them out and they were all a bright red. I guess it came from the fuel injector cleaner I had put in, or the water injection I had put on, don't know which. Less than 7500 miles on them, popped old ones back in just for a quickie test and runs great. Just a guess but that did it.
Again thanks.
Tim
