Check that you have the firing order correct as this will cause any car to run rough on idle!
If this fails then it could be a case that your spark plug gaps are too close/ far apart from what they should be to get correct spark!
Another good thing to check is the colour of the spark plugs to see if there is soot on the plugs as this could be a sign that the car is running too rich
