Default partially blocked cat?

erratic fuel economy regardless of driving style
random acceleration patterns (sometimes it will take off like a bat out of hell, other times it will crawl) when floored
it seems like i have lost some power
sometimes it feels like im bogged down
my air/fuel ratio is screwed(fouling plugs like a mother)

diagnosis: partially blocked catalytic converter. will do knock test. any other possibilities, or ideas?
