I would check your motor mounts. Does it shake when idling and driving through all rpms. A better description of the problem would help. WHen you say running rough does it have throttle issues ect.
yea i would say check your motor mounts to start, then check your ignition system. reseat all of your spark plugs and spark plug wires, where they plug into the distributor and where they attach to the plugs to themselves. if that doesn't do anything, try replacing your distributors. a nice upgrade would be the screamin demon distributors. they are 100 bucks for both of them, and provide a better spark than stock. that should work.
