rough idle makes me want to say the fuel pump is bad. you can check the fuel filter for clogs. also check you fuel pressure before the engine and see if it has enough pressure. I am positive that it is in the fuel delivery system mainly the pump. hope this helps update on what it was so people with the same issue can use this as a reference.
