What I'm trying to say, and apparently not well, sorry about that, is that the air fuel ratio being off causes there to be a thermal side effect. But it's the chemical a/f ratio that must be right for the cat to work. | |

The heat is a by product of having the right air / fuel ratio, but the correct ratio is what lets the catalytic work correctly. I believe @Zaid is posting something soon that explains it better than I am here. | |
