Tricky Tribeca: Mystery MISFIRES...+ OVERHEATING?? (Subaru H6)

This 2010 Subaru Tribeca H6 is not feeling too well at 140k miles...
Owner says that is it sputtering and LOSING POWER cruising around town at lower rpms.
Also, he said that the radiator has been BLOWN for a while, and he keeps adding coolant by the GALLON.

Let's take this Limping Subaru for a short test drive and see what we're dealing with.
Hopefully we can diagnose the misfire complaint before it BLOWS UP!!
