I have no idea but judging by the poor throttle response and a cheap way to atleast try something - fill up your gas tank and pour in a bottle of fuel injector cleaner. I'm no mechanic and I've never heard of anything like that happening all at once but...it's only like $5 tops for injector cleaner and you gotta fill your tank up eventually, and it won't hurt to clean them out anyway.
