I don't think that's my problem, as my engine only has about 6,000 miles 
on it.? When we pulled the engine @ over 100K miles there wasn't a lot 
of carbon buildup (but that engine had low compression to start).? My 
recent trips have been relatively short--100 miles or less--and it's 
possible I got a tank of 'bad' gas.

Thanks for all the replies.

Bob
