Diesel fuel in gas vehicle

Friend pumped 10 gallons of diesel into a 13 gallon Civic, engine stopped withing a few minutes. Mechanic drained, re-filled with 10 gallons of fresh gasoline, cleaned gas lines and changed both fuel filters, but now Civic is running rough. What damage? Rocketman

More than likely the plugs and injectors are fouled. Replace the plugs and dump a bottle of Techron in the tank.

Lots of info for you here:

The plugs are probably all fouled up. Have they been looked at? Fuel pressue good? Maybe the injectors are also fouled up?

Thanks folks! Rocketman
