I filled it up with E85 again today, had the laptop with so I could adjust for the new mixture in the tank (still diluting gas out of tank). Everything was running fine until during a cruise my fuel trims start going crazy, my wideband was showing that it wasnt cutting fuel on decel. I pulled off and let it idle, something was definitely wrong. The car would barely idle, So I pulled the vacuum line of my AFPR, yup it was dumping fuel in the vacuum line. Threw on a stock regulator and its good to go.

I'm going to pull the AFPR apart tomorrow to see what's going on with the diaphragm. I'm wondering if the E85 has anything to do with the sudden failure of the regulator.
