Since I can't seem to find anything definitive on the web or in the archives, I'd like to try and put together a list of some of the textboox symptoms for rich and lean mixtures.

Seems like it would be useful to those who know there car isn't running right and need help with diagnosis.


running lean: backfiring? hesitation? high idle etc?

running rich: black exhaust? low idle and bogging? poor gas economy?


somebody drop some knowledge for the archives....
