What are the misfire counts for each cylinder?

Some scan tools LIE about P0300. The "real" code may be P0301--P0308, but the tool just says "P0300".

True random missfire.

How can you know that unless you've got the misfire counts for each cylinder?

It could.

He didn't ask if you installed a new distributor. He asked if you adjusted it properly so the cam sensor signal is synchronized to the crank sensor signal. Spec is within 2 degrees at ~1100 rpm.
