If by accident you used diesel fuel, I'm surprised it is running. First, chances are you didn't ruin the engine. However, you need to have the fuel removed from the fuel system. The fuel tank should be removed, emptied, and cleaned out. The fuel lines from the fuel rail back should be blown out with compressed air, and the fuel filter will need replaced. I have a feeling the engine had a serious misfire going on, and that is why you felt and heard the problems. Once everything is cleaned out, if it still misses, replace the spark plugs.

Let me know if you have other questions.
