Your progression sounds good. But you need to figure out why #6 is misfiring. It could be a bad conductor in the cap, a bad wire, or a bad plug.

Manifold Absolute Pressure sensor. It detects the manifold vacuum and the pressure of the air entering the engine. It's on the air hose between the air filter and intake manifold. You can remove it and clean it. But don't touch it. A malfunctioning MAP sensor will cause the computer to either inject too much or not enough fuel.
