F150 7700 XL 5.4 Triton Bi-Fuel. Just filled up the truck both gas and propane. What happened the 80% did not shut off and ended up putting about 20 litres more propane that it should have taken. As soon as I left the station I had a bucking bronco for a ride. was hoping it would stop after driving 100 km. It has not. but 3 codes came up first P0000 then P0301 cyldr 1 misfire detected and the P0000 for the 3rd one. my book does not show what P0000 is. Does anyone know what P0000 code is Tried a search but did not see what I was looking for.
It shouldn't have showed up in the scanner, and if it did, cylinder 1 misfire should not have shown. Perhaps try disconnecting the battery and taking it for a ride to see what comes back. If no self diagnostic failure is indicated, it shouldn't tell anything to the scanner except "no code" or "0" or something along those lines (depending on scanner type/model).
If you had no issue before refueling, the over pressure in the propane tank set you up for a problem.
Release the pressure to normal levels and see if the problem goes away.
Your bi-fuel system is very complex and may have responded to the overpressure.
