Did the car run good before the tune up ? If so then something you did is not correct, whether it be a loose plug wire, bad plug gap or incorrect cap or rotor positioning. Recheck all your work BEFORE you take anything else apart.

Oh no it was much worse the car just shook and wouldn't go over 30 . Now the car is fast but idylls rough. Takeoff is smooth
