What do you all think. In my sig is my setup. Recently I've been having an issue of loss of significant power. I found a plug wire arking and fixed that but still no power (cant break tires loose from a stop no power). I dont have a tune, stock injectors, stock MAF, and stock fuel pump so I know those are contributing factors (if not the problem by itself). I mixed 3 gallons of e85 with 10 gallons of 93 octain and walla. Tons of power after that. I got excited until the next morning... no power. That afternoon after work the power was back. I checked all plug wires and electrical plugs but all was ok. this morning again, no power. Im thinking when its cool out (morning) a sensor somewhwere is hurting it somehow because when is hot out (like 96 yesterday) I have a hard time getting traction. What do you all think? New motor and tuner coming soon, but I still like to troubleshoot things for my library later on.
