Not much.
Code 300 is for a random miss. The engine computer has detected more than one cylinder that is not producing power, but no one cylinder is constant.
Until you get a code like 301 or 303 its a guessing game. 301-306 would tell you which cylinder is being the problem.
The cause could be fuel or spark.

P0300 is a random misfire and P0316 is misfire at start-up.
If you have the V6, I would start by replacing the plugs and all the coils.
This is a little ******* the V6, since you have to remove the intake manifold, and the coils can be expensive. Coils are available on Ebay.
I've replaced all the coils on my 2002 Escape V6 after 100,000 miles. Typical V6 problem.

Generally, the issue could be the following from: http://www.obd-codes.com/p0300
