Do you have a rough Idle or rough running at speed? If its idle you can use a squirt gun full of water to spray all the vacuum hoses on at a time that should show up any leaks until the water is sucked in, then it will go back to rough idle. For rough at speed, it could be the distributor I would suspect the dist shaft bushing ,test it by removing the cap and grab the rotor and see if it moves or wobbles . just a guess
