Hi Bill,
 That is quite a ways from here so it is not anyone I have heard of 
before. Well I guess you could use GM Top Engine Cleaner and let it soak 
in to see if it clears up the problem. Pretty powerful stuff. We used it 
on 2.5 liter engines to eliminate detonation from carbon back in my 
dealer days. But than again, as sharp as this guy is he may have tried 
that. Yea, right.
