    HELP!?!?!- knocking noise and gas smell

    hey everyone, kind of stuck in a jam here. was driving around today when out of nowhere the engine in my 04 4.0 started a violent knock. it threw a misfire code for the 3rd cylinder and i swapped the plug. now it is still knocking and there is a distinct smell of gas. can someone please...
