I have a CEL for (bank 1 lean), I believe its a common issue. I already change spark plugs, both O2's and its still there. I think it could be related to my FMIC set up because when I reverted back to stock, the code went away. Also it goes away when the weather gets hot. Now that I changed it back, is back on again. The strange thing is, it never threw any codes before until recently. Has this happen to anyone, if so what did you do to?
