The ignition timing is not adjustable on this year. If you turn the distributor, you will only throw the fuel injecters out of synch and put the check engine light on.
The base timing is determined by the Crankshaft Position Sensor.
The timing is not off, the injecter synchronization is along with the ignition synch.
You will need a professional scan tool to adjust this, not just a generic code reader.
Here are the instructions.
