CYP Sensor (Cylinder)
defective circuit or unplugged / defective sensor

1. Bad valve stem seals allow excessive oil in the combustion chamber and cause this oil to burn so you would see smoke as a sign of this. So NOT IT.
2. Distributor Cap - Visually inspect this for any cracks - if yes then replace it.
3. Distributor Rotor - Check for carbon deposits, if its all burned, replace it. Make sure the screw holding this is tight so rotor won't come off once you start the car.
4. Spark Plug Wires - In a dark place/garage open the hood and start the car. Look for any electric leaks along the wires, you'll see blue lightning like stuff if there are any leaks - if yes, replace wires.
5. Check Ignition timing using a Timing light - this could be off - use a repair manual to adjust it.
6. If all this checks out fine then unfortunately its the Cyl position sensor in your distributor housing that needs to be replaced.

hope this helps
