SOURCE: missfire in cylinder 2
I assume you know the problem is a misfire in #2 cylinder from checking the diagnostics code. Although these codes can be helpful in narrowing down a problem they lack specific details. In the case there are several possible items that could trigger the engine fault code P0302
These are the no or low cost options. Beyond these you will need to start replacing items like the Ignition Coil and O2 sensor.
If you are still having the problem after checking and/or replacing the items listed above, your next step is a compression test on #2 cylinder.
If you get to this point please repost here with the results with the wires and plugs and I will give you the steps to follow with compression testing.
Hope this helps.

When you change the plug what color is the tip of the old one? This could be the answer to your problems. It should be a light beige or tan if everything is working properly.Just take one of the old plugs down to your local garage and get the mechanic to have a look at it. He'll be able to tell you why it keeps misfiring. Hope this helps.
