Hey all, I did a search on this code and nothing came up, so if this is indeed a repeat post, please forgive me. Anyway, I got this code on my way to work today in my 99 Blazer LS (4.3L) 4X4. It shows up as Evap. Emissions leak (Small leak). Has anyone encountered this before. Where is a good place to start looking? Thanks in advance for the help.
