Isn't P0300 a random/multiple cylinder missfire?

Check the condition of the plugs, HT leads, coil, dizzy cap and rotor arm.

A vacuum leak can also cause this but would have to be a fairly large one.

I assume you are getting fuel to the rail?

P0300 Random/Multiple Cylinder Misfire Detected

When were the plugs last changed?

Any water / oil under the spark plug cover?
