P0303 probelm

So I have a slight misfire on third cylinder. The problem that I am having is that the spark plugs look fine and the electrode is still good. Now I think it might be the coil pack. I believe I check the coil pack with a multimeter. How exactly do I do this and what power rating should I look for?

Sorry if there is any errors in this post.

Easier test. Swap cyl 3 coil pack with another cylinder. See if the misfire follows the coil pack or not.

If you find its a bad coil, try this first. My electrode looked good too until it got really bad....
