Seafoam works very good for cleaning the combustion chamber, as well as
the intake. It used to be pretty hard to find, but now I think you can
get it at just about any FLAPS.
I had an old Honda Civic years ago that had a clogged EGR passage, and
my BIL had this factory GM stuff that he used to clean it out. Not sure
if you can get it at a local dealer or not though, and I can't remember
the proper name or part number. It was pretty potent stuff, a little
went a long way.
