NISSAN 200SX SENSOR PROBLEM

1995 Nissan 200SX • 187,600 miles

My check engine light is on, the code reader says that speed sensor. So I replace it with a new one, when I start it, the engine runs rough and the idle is playing. Is the speed sensor cause this? Does it to be align? I put back the screw back in and I dont see anything that I have to align it. But before that I replace the speedsensor the car wont start, the battery is good is just no spark! I do some research that it might be the spark plug/wires, so I replace them out too! But then after that the car runs rough. Pls help!

Check for vacuum leaks and check the idle air control valve.
