Thanks for your suggestion, Tony,

I'll ask my AME to check the plugs, as well as the fuel injection
system. And I'll try the forum you suggested.

Hi Chuck

Suggest you pull all of the plugs & examine them - I believe that you
will find at least some of them are black from running too rich.

I also suggest that you also post your question at:
http://www.cessnaowner.org/new/forum/forums.htm

There is a ton of Cessna knowledge there.
