If I remember correctly, E85 will eat the seals in the fuel system unless
your vehicle was designed to use E85. Fixing that will be way more
expensive than using regular gasoline at $2.50/gal.
Having said that, if you don't leave it in very long, i.e. you burned
through the tank quickly, you shouldn't have done major damage to the fuel
system. I don't know what effect it may or may not have on the Catalytic
converter. You should go to AutoZone or somesuch and have them pull the
codes. I'm betting that the oxygen sensors read something funny...
