Great! Thanks, chief! You have been a lot of help to me. Let me get to cleaning and see how it goes.

Seafoam basically eats away at carbon deposits that accumulate in your engine and clog it up. They can accumulate on pistons, in the intake manifold, clog up the EGR valve, basically anywhere that exhaust gas will travel. So everywhere inside your engine. If used properly it eats this away. If used improperly (too often), it'll kill your catalytic converter. I use it every 30k miles when I change my NGK V-Power plugs. Always change your spark plugs after you use it because it does mean stuff to them, too.
