Ok I've tried and tried and tried to find mccc.. Can't find it anyware.. I hear it's been discontinued  . I hear nothing good about seafoam (as a ccc) so I did ssome Internet searching and found this stuff from amsoil http://www.amsoil.com/storefront/apf.aspx Has anybody used this.. How did it work.. Blah blah blah. Or where can I get some mccc thanks in advance

 

Jut go with Seafoam or go to a GM dealer and get their Top Engine cleaner.

 

Ok I found a can of mccc on eBay.. Worked great smoked like crazy. Now my SES light is on.. Any ideas y?
