this all depends on how much regular petrol was in the tank before you added the E85
as you can get away with about 20% ethanol in regular fuel with no ill effects so its not like putting petrol in a diesel engine
e85 won't actually harm the engine but the ECU needs adjusting to cope with it so if its misfiring and struggling to accelerate then the fuel will have to be siphoned out and re-filled with fresh
do you still need help?
