Hold on a minute! Don't replace the sensors until you've checked/repaired any potential vacuum leaks. Your sensors are likely fine, they're just telling the engine to pump in too much gas to use the unmetered air that's being sucked into the engine. Search here on "vacuum" and you'll find scads of posts on vacuum leaks, the nemesis of fuel injected engines, and likely culprits, starting with all the little rubber elbows that crack and fail with age (kinda like me).
