Nissan Altima running rough?

My car's check engine light started blinking it was misfiring a cylinder (or so I believe, not too mechanically inclined). The valve cover was leaking oil down to the spark plugs and ignition coils. Well I replaced the valve cover, valve cover gasket, the spark plugs, and all the ignition coils. Well the car is idling rough. Almost shutting off at times. Running down the road it seems fine. What could be he problem now?

    your first step should have been to have a parts store attach the OBD code reader to see what code(s) is/are showing, so you know what needs to be repaired.............you can still have the reader do a scan and maybe save some $$
