New to E85. Getting a baseline...

[scheides]

The car must be extremely rich if you are hitting those IDC's, or you have a limitation in your fuel system somewhere. You have a walbro pump in the tank I assume? I'm not aware of any weird fuel line issues but sometimes after switching to E85 the fuel filter can become clogged. The best thing I can recommend is a wideband, the next would be to just watch your o2 feedback/fuel trims and see how far off it is...you're logging this thing, right?
