not sure what my problem is help?

[ch4d]

So in short i am driving back from Mcdoanalds And i come up to the speed limit car starts back firing and stalls wont idle but will crank all day long what the hell could it be? fuel pump? i dont want to jump to conclusions but if i can get more info on it that would be great thanks guys.


Edit: This morning poured gas in the throttle body and :BOOM:! black smoke. So from my dads and i conclusion we think it jumped time.
