    My car felt bit rough

    When I driving and stop at the red lights, so I felt the engine is bit rough, I think carb might be faultly?? could be problem with choke?

    I already replaced PCV, air filter, new spark plugs, and rotors.

    What is your thought?

        Need more information. How old is the fuel filter? How old are the plug wires? Have you ever had anyone adjust the carb? They do need a bit of tuning sometimes with age.

          I forgot to add two more: my car got new fuel filter and spark plug wires already. I still have original Ford's factory spark plug wires, but I put it in the box. its 26 years old.
